Summary

Returns X to the power N.

Pascal

 function PowerInt(const X: Float; N: Integer): Float; overload;
function PowerInt(const Z: TPolarComplex; const Exponent: Integer): TPolarComplex; overload;

Parameters

Parameters	Description
const X: Float	Base value.
N: Integer	Exponent.

Return Value

X to the power N.

Description

PowerInt calculates X to the power N where N is an integer. This function uses multiplication to raise X to the power N which is faster than using the formal formula for Power (which uses Exp and Ln) and therefore you should favor this function over Power when the exponent is an integer.
