pow() Math Calculation Web & Application 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 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. pow(base, exponent) base int or float: base of the exponential expression exponent int or float: power of which to raise the base float sqrt() 1.0 Function PDE
