Name

pow()

Description

Facilitates exponential expressions. The pow() function is an efficient way of multiplying numbers by themselves (or their reciprocal) in large quantities. For example, pow(3, 5) is equivalent to the expression 3*3*3*3*3 and pow(3, -5) is equivalent to 1 / 3*3*3*3*3.

Examples

float a = pow( 1, 3);  // Sets 'a' to 1*1*1 = 1
float b = pow( 3, 5);  // Sets 'b' to 3*3*3*3*3 = 243
float c = pow( 3,-5);  // Sets 'c' to 1 / 3*3*3*3*3 = 1 / 243 = .0041
float d = pow(-3, 5);  // Sets 'd' to -3*-3*-3*-3*-3 = -243

Syntax

pow(n, e)

Parameters

n(float)base of the exponential expression
e(float)power by which to raise the base

Return

float

sqrt()
