# 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 3*3*3*3*3 and pow(3, -5) is equivalent to 1 / 3*3*3*3*3.

##### Code:

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
