frexp(3m)

Mathematical Library Functions                                       frexp(3M)



NAME
       frexp,  frexpf, frexpl - extract mantissa and exponent from a floating-
       point number

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double frexp(double num, int *exp);


       float frexpf(float num, int *exp);


       long double frexpl(long double num, int *exp);

DESCRIPTION
       These functions break a floating-point number into a  normalized  frac‐
       tion and an integral power of 2. They store the integer exponent in the
       int object pointed to by exp.

RETURN VALUES
       For finite arguments, these functions return the value x, such  that  x
       is  a double with magnitude in the interval [½, 1) or 0, and num equals
       x times 2 raised to the power *exp.


       If num is NaN, NaN is returned and the value of *exp is unspecified.


       If num is ± 0, ± 0 is returned and the value of *exp is 0.


       If num is ±Inf, num is returned and the value of *exp is unspecified.
