NAME
       frexp(),	 frexpf(), frexpl(), frexpw(), frexpq() - extract mantissa and
       exponent from floating-point number

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The function breaks a floating-point number into a normalized  fraction
       and  an	integral  power	 of  2.	 It stores the integer exponent in the
       object pointed to by exp.

   Integrity Server Only
       is a version of it takes a first argument and returns a result.

       is an version of it takes an first argument and returns an result.   is
       equivalent to on HP-UX systems.

USAGE
       To  use	(for Integrity servers) compile either with the default option
       or with the option.

       To use (for Integrity servers) compile either with the  default	option
       or with the and options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes and link
       in the math library by specifying on the	 compiler  or  linker  command
       line.  For more information, see the at the following site:

RETURN VALUE
       The  function  returns  the value x, such that x is a with magnitude in
       the interval [0.5, 1] or zero, and value equals x times 2 raised to the
       power *exp.

       If  value  is zero, returns value and stores zero in the object pointed
       to by exp.

       If value is NaN, returns NaN, and the value of *exp is unspecified.

       If value returns value, and the value of *exp is unspecified.

       These functions raise no exceptions.

ERRORS
       No errors are defined.
