public static double sqrt(double x)
Java Math.Sqrt () is a inbuild static method. it returns the square root of a number. It is present in Java.lang.Math.
- If the parameter is positive double value this method will return the square root of a given value.
- If the parameter is NaN or less than zero, this method will return NaN.
Example 1
public class Program
{
public static void main(String []args)
{
System.out.println("Math.sqrt(64) = "+ Math.sqrt(64));
System.out.println("Math.sqrt(64L) = "+ Math.sqrt(64L));
System.out.println("Math.sqrt(64f) = "+ Math.sqrt(64f));
System.out.println("Math.sqrt(64.0) = "+ Math.sqrt(64.0));
System.out.println("Math.sqrt(10) = "+ Math.sqrt(10));
System.out.println("Math.sqrt(10L) = "+ Math.sqrt(10L));
System.out.println("Math.sqrt(10f) = "+ Math.sqrt(10f));
System.out.println("Math.sqrt(10.0) = "+ Math.sqrt(10.0));
}
}Math.sqrt(64) = 8.0 Math.sqrt(64L) = 8.0 Math.sqrt(64f) = 8.0 Math.sqrt(64.0) = 8.0 Math.sqrt(10) = 3.1622776601683795 Math.sqrt(10L) = 3.1622776601683795 Math.sqrt(10f) = 3.1622776601683795 Math.sqrt(10.0) = 3.1622776601683795
Example 2
public class Program

System.out.println("Math.sqrt(-64.0) = "+ Math.sqrt(-64.0));
System.out.println("Math.sqrt(-10) = "+ Math.sqrt(-10));
System.out.println("Math.sqrt(-10L) = "+ Math.sqrt(-10L));
System.out.println("Math.sqrt(-10f) = "+ Math.sqrt(-10f));
System.out.println("Math.sqrt(-10.0) = "+ Math.sqrt(-10.0));
}
}Math.sqrt(-64) = NaN Math.sqrt(-64L) = NaN Math.sqrt(-64f) = NaN Math.sqrt(-64.0) = NaN Math.sqrt(-10) = NaN Math.sqrt(-10L) = NaN Math.sqrt(-10f) = NaN Math.sqrt(-10.0) = NaN
