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 fraction 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 [1/2, 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.
