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 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(base, exponent)
   
Parameters  
base   int or float: base of the exponential expression
exponent   int or float: power of which to raise the base

   
Returns   float
