pow()

Description

Facilitates exponential expressions. The pow() function is an efficient way of multiplying numbers by themselves (or their reciprocals) in large quantities. For example, pow(3, 5) is equivalent to the expression 33333 and pow(3, -5) is equivalent to 1 / 33333.

Example

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
