pow()

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.
Syntax
pow(num, exponent)
Parameters
num int or float: base of the exponential expression
exponent int or float: power of which to raise the base
Returns float
Usage Web & Application
Related sqrt()
