Java StrictMath - sqrt() Method
The java.lang.StrictMath.sqrt() method returns the square root of the given number. In special cases it returns the following:
- If the argument is NaN or less than zero, then the result is NaN.
- If the argument is positive infinity, then the result is positive infinity.
- If the argument is positive zero or negative zero, then the result is the same as the argument.
Syntax
public static double sqrt(double a)
Parameters
a |
Specify a value. |
Return Value
Returns the positive square root of a. If the argument is NaN or less than zero, the result is NaN.
Exception
NA.
Example:
In the example below, sqrt() method is used to find out the square root of the given number.
import java.lang.*; public class MyClass { public static void main(String[] args) { System.out.println(StrictMath.sqrt(25)); System.out.println(StrictMath.sqrt(30)); System.out.println(StrictMath.sqrt(35.5)); System.out.println(StrictMath.sqrt(-25)); } }
The output of the above code will be:
5.0 5.477225575051661 5.958187643906492 NaN
