    FREXP(3)	    UNIX Programmer's Manual		 FREXP(3)

    NAME
         frexp, ldexp, modf - split into mantissa and exponent

    SYNOPSIS
         double frexp(value, eptr)
         double value;
         int *eptr;

         double ldexp(value, exp)
         double value;

         double modf(value, iptr)
         double value, *iptr;

    DESCRIPTION
         Frexp returns the mantissa of a double value as a double
         quantity, x, of magnitude less than 1 and stores an integer
         n such that value = x*2n indirectly through eptr.

         Ldexp returns the quantity value*2exp.

         Modf returns the positive fractional part of value and
         stores the integer part indirectly through iptr.
