FREXP(3)            Linux Programmer's Manual            FREXP(3)
NAME
       frexp  -  convert  floating-point number to fractional and
       integral components
SYNOPSIS
       #include <math.h>
       double frexp(double x, int *exp);
DESCRIPTION
       The frexp() function is used to split the number x into  a
       normalized  fraction  and  an  exponent which is stored in
       exp.
RETURN VALUE
       The frexp() function returns the normalized fraction.   If
       the  argument  x is not zero, the normalized fraction is x
       times a power of two, and  is  always  in  the  range  1/2
       (inclusive) to 1 (exclusive).  If x is zero, then the nor-
       malized fraction is zero and zero is stored in exp.
