Defined in header <cmath>
float       exp( float arg );
double      exp( double arg );
long double exp( long double arg );
double      exp( Integral arg );
(since C++11)

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

Parameters

arg - value of floating-point or Integral type

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.
