Find Cube root of a number Using System.Math.Pow() method in C#

Question

While writing a program I came across finding the cube root of a number in one of my functions.

when I used the below code, I was getting an incorrect value for the

Answer 1

This is a standard trap in the { curly brace languages }, C# included, a division with integral operands is performed as an integer division, not a floating point division. It always yields an integer result, 1 / 3 produces 0. Raising any number to the power of 0 produces 1.0

You force a floating point division by converting one of the operands to double. Like 1.0 / 3 or (double)integerVariable / 3.

Similar problem with multiplication, but usually less of a trap, integral operands produce an integral result that risks overflow. This otherwise reflects the way the processor works, it has distinct instructions for these operations, IMUL vs FMUL and IDIV vs FDIV. The latter one being rather famous for a bug in the Pentium processor :)
