```EXP(3)			   Linux Programmer's Manual			EXP(3)

NAME
exp, expf, expl - base-e exponential function

SYNOPSIS
#include <math.h>

double exp(double x);
float expf(float x);
long double expl(long double x);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

expf(), expl():
_BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99

DESCRIPTION
The exp() function returns the value of e (the base  of	natural	 loga‐
rithms) raised to the power of x.

RETURN VALUE
On success, these functions return the exponential value of x.

If x is a NaN, a NaN is returned.

If x is positive infinity, positive infinity is returned.

If x is negative infinity, +0 is returned.

If the result underflows, a range error occurs, and zero is returned.

If the result overflows, a range error occurs, and the functions return
+HUGE_VAL, +HUGE_VALF, or +HUGE_VALL, respectively.

ERRORS
See math_error(7) for information on how to determine whether an	 error
has occurred when calling these functions.

The following errors can occur:

Range error, overflow
errno  is	 set  to ERANGE.  An overflow floating-point exception
(FE_OVERFLOW) is raised.

Range error, underflow
errno is set to ERANGE.  An underflow  floating-point  exception
(FE_UNDERFLOW) is raised.

CONFORMING TO
C99, POSIX.1-2001.  The variant returning double also conforms to SVr4,
4.3BSD, C89.

cbrt(3), cexp(3), exp10(3), exp2(3), sqrt(3)

COLOPHON
This page is part of release 3.65 of the Linux  man-pages  project.   A
