Defined in header <math.h>
float       expf( float arg );
(since C99)
double      exp( double arg );
long double expl( long double arg );
(since C99)

Computes the e (Euler's number, 2.7182818) raised to the given power arg

Parameters

arg - floating point value

Return value

e raised to the power arg

If the result is too large for the underlying type, range error occurs and HUGE_VAL is returned.
