# Using Math.Pow Method to Compute Exponents in C#

If you require to compute exponential values like finding the square of the number etc , the Math.Pow method in c# could be handy for you to try .

The Math.Pow method is defined in the “System” namespace .

To use the method “Math.Pow” , you should first include the namespace System

`using System;`

The Math.Pow accepts 2 parameters

1. number to be raised to a power
2. number that specifies a power

Note that the parameters to the Math.Pow must be of type double .

For example , i can use the method

`double value1 = Math.Pow(3, 3);`

The above code is equivalent to 3 ^ 3 .

Below is a sample function that i used for my new WP7 App which uses the Math.Pow function

```private decimal CalclateEMI(decimal LoanAmount,int Months,double Interest)
{
Interest = (Interest / 100)/12;
decimal EMI = (LoanAmount * (Decimal)Interest) * (Decimal)( Math.Pow((1+ Interest), Months) / ((Math.Pow((1+ Interest ), Months)) - 1));
return EMI;
}```

Math.Pow is one of the useful method that provides a clear way to calculate exponential values ;
