frexp — split a floating point number
genType frexp( | genType x, |
out genIType exp); |
genDType frexp( | genDType x, |
out genIType exp); |
x Specifies the value from which significand and exponent are to be extracted.
out exp Specifies the variable into which to place the exponent
frexp extracts x into a floating-point significand in the range [0.5, 1.0) and in integral exponent of two, such that:
The significand is returned by the function and the exponent is returned in the output parameter exp. For a floating-point value of zero, the significand and exponent are both zero. For a floating-point value that is an infinity or a floating-point NaN, the results are undefined.
