Name | ### 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 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.
Syntax |
    pow(n, e)
Parameters |
n | float: base of the exponential expression
e | float: power by which to raise the base
Returns | float
Related | sqrt()
