# C# Math - Cbrt() Method

The C# Cbrt() method returns the cube root of the given number. In special cases it returns the following:

• If the argument is NaN, then method returns NaN.

### Syntax

```public static float Cbrt (float arg);
```

### Parameters

 `arg` Specify a number.

### Return Value

Returns the cube root of the specified number.

### Example:

In the example below, Cbrt() method is used to find out the cube root of the given number.

```using System;

class MyProgram {
static void Main(string[] args) {
Console.WriteLine("Math.Cbrt(64) = "
+ Math.Cbrt(64));
Console.WriteLine("Math.Cbrt(100) = "
+ Math.Cbrt(100));
Console.WriteLine("Math.Cbrt(-100) = "
+ Math.Cbrt(-100));
Console.WriteLine("Math.Cbrt(Double.NaN) = "
+ Math.Cbrt(Double.NaN));
Console.WriteLine("Math.Cbrt(Double.NegativeInfinity) = "
+ Math.Cbrt(Double.NegativeInfinity));
Console.WriteLine("Math.Cbrt(Double.PositiveInfinity) = "
+ Math.Cbrt(Double.PositiveInfinity));
}
}
```

The output of the above code will be:

```Math.Cbrt(64) = 4
Math.Cbrt(100) = 4.64158883361278
Math.Cbrt(-100) = -4.64158883361278
Math.Cbrt(Double.NaN) = NaN
Math.Cbrt(Double.NegativeInfinity) = -Infinity
Math.Cbrt(Double.PositiveInfinity) = Infinity
```
