exp(3M)			Mathematical Library Functions		       exp(3M)

NAME
       exp, expf, expl - exponential function

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double exp(double x);

       float expf(float x);

       long double expl(long double x);

DESCRIPTION
       These functions compute the base-e exponential of x.

RETURN VALUES
       Upon  successful	 completion,  these  functions	return the exponential
       value of x.

       If the correct value would cause overflow, a  range  error  occurs  and
       exp(),  expf(),	and  expl() return HUGE_VAL, HUGE_VALF, and HUGE_VALL,
       respectively.

       If x is NaN, a NaN is returned.

       If x is ±0, 1 is returned.

       If x is +Inf, x is returned.

       For exceptional cases, matherr(3M) tabulates the values to be  returned
       by exp() as specified by SVID3 and XPG3. See standards(5).

ERRORS
       These functions will fail if:

       Range Error     The result overflows.

		       If   the	  integer   expression	 (math_errhandling   &
		       MATH_ERREXCEPT) is  non-zero,  the  overflow  floating-
		       point exception is raised.

		       The  exp()  function sets errno to ERANGE if the result
		       overflows.

USAGE
       An application wanting to check for exceptions should  call  feclearex‐
       cept(FE_ALL_EXCEPT)  before  calling  these  functions.	On  return, if
       fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is
       non-zero,  an  exception	 has been raised. An application should either
       examine the return value or check the floating point exception flags to
       detect exceptions.

       An application can also set errno to 0 before calling exp(). On return,
       if errno is non-zero, an error has  occurred.  The  expf()  and	expl()
       functions do not set errno.
