The java.lang.Math.copySign() method returns the first argument with the sign of the second argument.
Note:
Arguments can be of two types:
- double type : copySign(double magt, double sign)
- float type : copySign(float magt, float sign)
Syntax :
public static double copySign(DataType magt, DataType sign) Parameter : magt: argument providing the magnitude of the result. sign : argument providing the sign of the result. Return : This method returns the magnitude of the first argument with the sign of the second argument.
Example :To show working of java.lang.Math.copySign() method.
// Java program to demonstrate working // of java.lang.Math.copySign() method import java.lang.Math;
class Gfg {
// driver code
public static void main(String args[])
{
double a = 34.543 ;
double b = - 123.44 ;
// Input a, b
// Output -34.543( a- Magnitude, b- Sign)
System.out.println(Math.copySign(a, b));
// Input b, a
// Output 123.44( b- Magnitude, a- Sign)
System.out.println(Math.copySign(b, a));
float c = 87 .56f;
float d = - 685 .23f;
// Input c, d
// Output -87.56( c- Magnitude, d- Sign)
System.out.println(Math.copySign(c, d));
// Input d, c
// Output 685.23( d- Magnitude, c- Sign)
System.out.println(Math.copySign(d, c));
}
} |
Output:
-34.543 123.44 -87.56 685.23
