Purpose
Elemental Intrinsic Function Returns powers of e.
Syntax
result = EXP (x)
x
(Input) Real or complex. Can be an array. Power to which e is raised.
Return Value
Same type and kind as x with a value e**x. If x is complex, its imaginary part is regarded as a value in radians: for example, if x = (a, b) the result is e**a (cos(b) + i sin(b)).
