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.

RETURN VALUE

       Upon successful completion, the function returns

       If x zero, or a NaN, returns x.

       returns a properly signed infinity in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions.

       raises the underflow and inexact exceptions whenever a result is tiny (essentially denormal or zero) and thereby suffers loss of  accuracy,
       and may raise those exceptions if the result is merely tiny.

ERRORS

       If the correct value would overflow, sets to [ERANGE].

   Integrity Server Only
       HP-UX functions on Integrity servers do not set by default.  For setting, compile with the option.
