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 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.
