<strong>FREXP, LDEXP<strong>
==SYNOPSIS==
#include <math.h>
double frexp(double f, int * p)
double ldexp(double f, int i)
==DESCRIPTION==
<strong>Frexp</strong>() breaks a floating point number into a normalized fraction and an integral power of 2. The integer
is stored into the int object pointed to by p. Its
return value x is in the interval [0.5, 1.0) or zero,
and f equals x times 2 raised to the power stored in
*p. If f is zero, both parts of the result are zero.
<strong>Ldexp</strong>() performs the reverse operation; the integer i
is added to the exponent of the floating point f and
the resultant value returned.
