NAME
       exp2(),	exp2f(),  exp2l(), exp2w(), exp2q() - base-2 exponential func‐
       tions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       returns

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

       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To use these functions, compile either with the default option or  with
       the and options.

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

       To use 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
       returns 1.

       If x is +INFINITY, returns +INFINITY.

       If x is −INFINITY, returns zero.

       If x is NaN, returns NaN.

       returns infinity (equal to 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.

       raises  the  inexact exception whenever a rounded result does not equal
       the mathematical result.

ERRORS
   Integrity Server Only
       If the correct value would overflow, sets to [ERANGE].

       HP-UX functions on Integrity servers do not set by default.   For  set‐
       ting, compile with the option.
