NAME
       frexp - convert floating-point number to	fractional and integral	compo-
       nents

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	normalized fraction is zero and	zero is	stored in exp.
