Java Math.sqrt - ashish9342/FreeCodeCamp GitHub Wiki
Description: Math.sqrt() method returns the square root value of the primitive data type. If a number is less than zero, it will return NaN.
double sqrt(double d)Contains primitive data type.
Returns the square root of argument.
Example:
public class Math {
public static void main(String[] args) {
double a = Math.sqrt(9); //calculates square root of 9
double b = Math.sqrt(2456.7); //calculates square root of 2456.7
double c = Math.sqrt(-4568); //calculates square root of -4568
System.out.println("Math Square root value :" + a);
System.out.println("Math Square root value :" + b);
System.out.println("Math Square root value :" + c);
}
}Output:
Math Square root value: 3.0
Math Square root value: 49.565108695532984
Math Square root value: NaN
