| 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 |

| 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. | ||||
