NAME
       exp(), expf(), expl(), expw(), expq() - exponential functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       returns

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

   Integrity Server Only
       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 the 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:

   PA-RISC Only
       Millicode versions of the functions are available.  Millicode versions of math library functions are usually faster than their counterparts
       in the standard library.  To use these versions, compile your program with the or the optimization option.

       For special cases, the millicode versions return the same values as their standard library counterparts (see the section), but do not set

RETURN VALUE
       returns 1.

       If x is +INFINITY, returns +INFINITY.

       If x is -INFINITY, returns +0.

       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.

       When it raises no other exception, whether raises the inexact exception is unspecified.

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.
