NAME

       frexp - split a floating point number

DECLARATION

       genType frexp(genType x, out genIType exp);

       genDType frexp(genDType x, out genIType exp);

PARAMETERS

       x
           Specifies the value from which significand and exponent are to be extracted.

       out exp
           Specifies the variable into which to place the exponent

DESCRIPTION

       frexp extracts x into a floating-point significand in the range [0.5, 1.0) and in integral exponent of
       two, such that:

       x = significand ⋅ 2 exponent

       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.
