C# Square Root Help

[MaximusX]

How can I calculate a square root of a number in c#?

[Stefan1024]

a = sqrt(x);

 

don't forget the math.h lib.

[MaximusX]

a = sqrt(x);

 

don't forget the math.h lib.

Could you give me some more example code?(new to c#)

Could you give me some more example code?(new to c#)

 

 

public double SquareRoot(double x)        {           return Math.Sqrt(x)        }

Simple function.

are you talking about c#.net? working in visual studio?
if yes, look above answer of @JuztBe

 

you can either put the Math.Sqrt in a function or use inline.

Don't forget to assign it to a variable.

 

double squareRoot = Math.Sqrt(x);

Or

double squareRoot = SquareRoot(x); //If using function as answered by @JuztBe

For standart C# finctions there are a lot of examples on the internet. Just google 2 minutes and you find it. It's faster than writhing a question here.

An example: http://www.dotnetperls.com/sqrt

Thanks this helped a lot, but how can I convert an int to a double?

double aDouble = Convert.ToDouble(a);

Don't be afraid of a google. You will be able to find everything you want.

You can declare x as int.

 

x as Double, was just as an example.

It can be int as well, but the result of square root could be double at times.

It's good to learn to use the documentation (and Google). Most programming languages have a basic Math library and C# is no different. Here is the documentation page for it which contains information on all the methods available in it. You can then click on the function you need for even more information if necessary. For example, here's the Sqrt function. Sqrt takes a double as a parameter and returns a double.

double d = Math.Sqrt(4.0);

Here is some information about casting and type conversions. You'll do it a lot when programming so it's good to learn more about it. int to double is an implicit cast, so you don't have to do anything special.

// this is valid and is an implicit castint i = 100;double d = i;// the other way around requires an explicit castdouble d = 10.8;int i = (int) d; // i contains 10 because the decimal place is truncated (ie: removed without any rounding)

So you can do something like this

int value = 100;int result = (int) Math.Sqrt(value);
