C MathSqrt Examples
In this tutorial, we will learn about the C# Math.Sqrt() method, and learn how to use this method to find the square root of given number, with the help of examples.
SqrtDouble
Math.Sqrt(d) returns the square root of a specified number d
.
Syntax
The syntax of Sqrt() method is
Math.Sqrt(Double d)
where
Parameter | Description |
---|---|
d | The number whose square root is to be found. |
Return Value
The method returns Double value.
Example 1 SqrtDouble
In this example, we will find the square root of some numbers using Sqrt() method.
C# Program
using System; class Example { static void Main(string[] args) { Double d, result; d = 2; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = 3; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = 4; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = 9; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = 16; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = 0.25; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = Double.NegativeInfinity; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); d = Double.PositiveInfinity; result = Math.Sqrt(d); Console.WriteLine($"Sqrt({d}) = {result}"); } }
Output
Sqrt(2) = 1.4142135623731 Sqrt(3) = 1.73205080756888 Sqrt(4) = 2 Sqrt(9) = 3 Sqrt(16) = 4 Sqrt(0.25) = 0.5 Sqrt(-∞) = NaN Sqrt(∞) = ∞
Conclusion
In this C# Tutorial, we have learnt the syntax of C# Math.Sqrt() method, and also learnt how to use this method with the help of C# example programs.
