exp(3M) Mathematical Library Functions exp(3M)
NAME
exp, expf, expl - exponential function
SYNOPSIS
cc [ 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 feclearexcept(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.
