The floatToRawIntBits() method in Float Class is a built-in function in java that 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.
public static int floatToRawIntBits(float val)
Parameter: The method accepts only one parameter val which specifies a floating-point number.
Return Values: The function returns the bits that represent the floating-point number. However there are 3 special cases:
- 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.
Below programs illustrates the use of Float.floatToRawIntBits() method:
1.5 in raw int bits: 1069547520
Infinity in raw int bits: 2139095040 -Infinity in raw int bits: -8388608 NaN in raw int bits: 2139095040
