Float class wraps a value of primitive type
float in an object. An object of type
Float contains a single field whose type is
float.
In addition, this class provides several methods for converting a
float to a String and a
String to a float, as well as other
constants and methods useful when dealing with a
float.
This is a value-based class; programmers should treat instances that are equal as interchangeable and should not use instances for synchronization, or unpredictable behavior may occur. For example, in a future release, synchronization may fail.
Floating-point Equality, Equivalence, and Comparison
The classjava.lang.Double has a discussion of equality,
equivalence, and comparison of floating-point values that is
equality applicable to float values.- Since:

Method Details
-
toString
Returns a string representation of thefloatargument. All characters mentioned below are ASCII characters.- If the argument is NaN, the result is the string
"
NaN". - Otherwise, the result is a string that represents the sign and
magnitude (absolute value) of the argument. If the sign is
negative, the first character of the result is
'
-' ('\u002D'); if the sign is positive, no sign character appears in the result. As for the magnitude m:- If m is infinity, it is represented by the characters
"Infinity"; thus, positive infinity produces the result"Infinity"and negative infinity produces the result"-Infinity". - If m is zero, it is represented by the characters
"0.0"; thus, negative zero produces the result"-0.0"and positive zero produces the result"0.0". - If m is greater than or equal to 10-3 but
less than 107, then it is represented as the
integer part of m, in decimal form with no leading
zeroes, followed by '
.' ('\u002E'), followed by one or more decimal digits representing the fractional part of m. - If m is less than 10-3 or greater than or
equal to 107, then it is represented in
so-called "computerized scientific notation." Let n
be the unique integer such that 10n ≤
m < 10n+1; then let a
be the mathematically exact quotient of m and
10n so that 1 ≤ a < 10.
The magnitude is then represented as the integer part of
a, as a single decimal digit, followed by
'
.' ('\u002E'), followed by decimal digits representing the fractional part of a, followed by the letter 'E' ('\u0045'), followed by a representation of n as a decimal integer, as produced by the methodInteger.toString(int).
- If m is infinity, it is represented by the characters
float. That is, suppose that x is the exact mathematical value represented by the decimal representation produced by this method for a finite nonzero argument f. Then f must be thefloatvalue nearest to x; or, if twofloatvalues are equally close to x, then f must be one of them and the least significant bit of the significand of f must be0.To create localized string representations of a floating-point value, use subclasses of
NumberFormat.- Parameters:
f- the float to be converted.- Returns:
- a string representation of the argument.
- If the argument is NaN, the result is the string
"
-
toHexString
Returns a hexadecimal string representation of thefloatargument. All characters mentioned below are ASCII characters.- If the argument is NaN, the result is the string
"
NaN". - Otherwise, the result is a string that represents the sign and
magnitude (absolute value) of the argument. If the sign is negative,
the first character of the result is '
-' ('\u002D'); if the sign is positive, no sign character appears in the result. As for the magnitude m:- If m is infinity, it is represented by the string
"Infinity"; thus, positive infinity produces the result"Infinity"and negative infinity produces the result"-Infinity". - If m is zero, it is represented by the string
"0x0.0p0"; thus, negative zero produces the result"-0x0.0p0"and positive zero produces the result"0x0.0p0". - If m is a
floatvalue with a normalized representation, substrings are used to represent the significand and exponent fields. The significand is represented by the characters"0x1."followed by a lowercase hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed unless all the digits are zero, in which case a single zero is used. Next, the exponent is represented by"p"followed by a decimal string of the unbiased exponent as if produced by a call toInteger.toStringon the exponent value. - If m is a
floatvalue with a subnormal representation, the significand is represented by the characters"0x0."followed by a hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed. Next, the exponent is represented by"p-126". Note that there must be at least one nonzero digit in a subnormal significand.
- If m is infinity, it is represented by the string

Returns aFloatobject holding thefloatvalue represented by the argument strings.If
sisnull, then aNullPointerExceptionis thrown.Leading and trailing whitespace characters in
sare ignored. Whitespace is removed as if by theString.trim()method; that is, both ASCII space and control characters are removed. The rest ofsshould constitute a FloatValue as described by the lexical syntax rules:

pP
sdoes not have the form of a FloatValue, then aNumberFormatExceptionis thrown. Otherwise,sis regarded as representing an exact decimal value in the usual "computerized scientific notation" or as an exact hexadecimal value; this exact numerical value is then conceptually converted to an "infinitely precise" binary value that is then rounded to typefloatby the usual round-to-nearest rule of IEEE 754 floating-point arithmetic, which includes preserving the sign of a zero value. Note that the round-to-nearest rule also implies overflow and underflow behaviour; if the exact value ofsis large enough in magnitude (greater than or equal to (MAX_VALUE+ulp(MAX_VALUE)/2), rounding tofloatwill result in an infinity and if the exact value ofsis small enough in magnitude (less than or equal toMIN_VALUE/2), rounding to float will result in a zero. Finally, after rounding aFloatobject representing thisfloatvalue is returned.To interpret localized string representations of a floating-point value, use subclasses of
NumberFormat.Note that trailing format specifiers, specifiers that determine the type of a floating-point literal (
1.0fis afloatvalue;1.0dis adoublevalue), do not influence the results of this method. In other words, the numerical value of the input string is converted directly to the target floating-point type. In general, the two-step sequence of conversions, string todoublefollowed bydoubletofloat, is not equivalent to converting a string directly tofloat. For example, if first converted to an intermediatedoubleand then tofloat, the string
"1.00000017881393421514957253748434595763683319091796875001d"
results in thefloatvalue1.0000002f; if the string is converted directly tofloat,1.0000001fresults.To avoid calling this method on an invalid string and having a
NumberFormatExceptionbe thrown, the documentation forDouble.valueOflists a regular expression which can be used to screen the input.- Parameters:
s- the string to be parsed.- Returns:

Floatobject holding the value represented by theStringargument. - Throws:
NumberFormatException- if the string does not contain a parsable number.

valueOf

- This method is defined in terms of

floatToIntBits
public static int floatToIntBits(float value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.Bit 31 (the bit that is selected by the mask
0x80000000) represents the sign of the floating-point number. Bits 30-23 (the bits that are selected by the mask0x7f800000) represent the exponent. Bits 22-0 (the bits that are selected by the mask0x007fffff) represent the significand (sometimes called the mantissa) of the floating-point number.If the argument is positive infinity, the result is
0x7f800000.If the argument is negative infinity, the result is
0xff800000.If the argument is NaN, the result is
0x7fc00000.In all cases, the result is an integer that, when given to the
intBitsToFloat(int)method, will produce a floating-point value the same as the argument tofloatToIntBits(except all NaN values are collapsed to a single "canonical" NaN value).- Parameters:
value- a floating-point number.- Returns:
- the bits that represent the floating-point number.
-
floatToRawIntBits
public static int floatToRawIntBits(float value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.Bit 31 (the bit that is selected by the mask
0x80000000) represents the sign of the floating-point number. Bits 30-23 (the bits that are selected by the mask0x7f800000) represent the exponent. Bits 22-0 (the bits that are selected by the mask0x007fffff) represent the significand (sometimes called the mantissa) of the floating-point number.If the argument is positive infinity, the result is
0x7f800000.If the argument is negative infinity, the result is
0xff800000.If the argument is NaN, the result is the integer representing the actual NaN value. Unlike the
floatToIntBitsmethod,floatToRawIntBitsdoes not collapse all the bit patterns encoding a NaN to a single "canonical" NaN value.In all cases, the result is an integer that, when given to the
intBitsToFloat(int)method, will produce a floating-point value the same as the argument tofloatToRawIntBits.- Parameters:
value- a floating-point number.- Returns:
- the bits that represent the floating-point number.
- Since:
- 1.3
-
intBitsToFloat
public static float intBitsToFloat(int bits) Returns thefloatvalue corresponding to a given bit representation. The argument is considered to be a representation of a floating-point value according to the IEEE 754 floating-point "single format" bit layout.If the argument is
0x7f800000, the result is positive infinity.If the argument is
0xff800000, the result is negative infinity.If the argument is any value in the range
0x7f800001through0x7fffffffor in the range0xff800001through0xffffffff, the result is a NaN. No IEEE 754 floating-point operation provided by Java can distinguish between two NaN values of the same type with different bit patterns. Distinct values of NaN are only distinguishable by use of theFloat.floatToRawIntBitsmethod.In all other cases, let s, e, and m be three values that can be computed from the argument:
Then the floating-point result equals the value of the mathematical expression s·m·2e-150.int s = ((bits >> 31) == 0) ? 1 : -1; int e = ((bits >> 23) & 0xff); int m = (e == 0) ? (bits & 0x7fffff) << 1 : (bits & 0x7fffff) | 0x800000;Note that this method may not be able to return a
floatNaN with exactly same bit pattern as theintargument. IEEE 754 distinguishes between two kinds of NaNs, quiet NaNs and signaling NaNs. The differences between the two kinds of NaN are generally not visible in Java. Arithmetic operations on signaling NaNs turn them into quiet NaNs with a different, but often similar, bit pattern. However, on some processors merely copying a signaling NaN also performs that conversion. In particular, copying a signaling NaN to return it to the calling method may perform this conversion. SointBitsToFloatmay not be able to return afloatwith a signaling NaN bit pattern. Consequently, for someintvalues,floatToRawIntBits(intBitsToFloat(start))may not equalstart. Moreover, which particular bit patterns represent signaling NaNs is platform dependent; although all NaN bit patterns, quiet or signaling, must be in the NaN range identified above.- Parameters:
bits- an integer.- Returns:
- the
floatfloating-point value with the same bit pattern.
-
compareTo
Compares twoFloatobjects numerically. This method imposes a total order onFloatobjects with two differences compared to the incomplete order defined by the Java language numerical comparison operators (<, <=, ==, >=, >) onfloatvalues.- A NaN is unordered with respect to other
values and unequal to itself under the comparison
operators. This method chooses to define
Float.NaNto be equal to itself and greater than all otherdoublevalues (includingFloat.POSITIVE_INFINITY). - Positive zero and negative zero compare equal
numerically, but are distinct and distinguishable values.
This method chooses to define positive zero (
+0.0f), to be greater than negative zero (-0.0f).
Floatobjects imposed by this method is consistent with equals; see this discussion for details of floating-point comparison and ordering.- Specified by:
