EXP Function

Raises e to the power of the value of the input variable.

result = EXP(x)

x The value to be evaluated.

result The natural exponential function of x.

None.

EXP is defined as:

y = e ^x

If x is of double-precision floating-point or complex data type, EXP yields results of the same type. All other types yield a single-precision floating-point result.

EXP handles complex values in the following way:

exp(x) = complex(e^rcos(i), e^rsin(i))

where r is the real part of x, and i is the imaginary part of x. If x is an array, the result has the same dimensions as x, with each element containing the result for the corresponding element of x.
