Java Math IEEEremainder() method with Examples

The java.lang.Math.IEEEremainder() method computes the remainder operation on two arguments as prescribed by the IEEE 754 standard.The remainder value is mathematically equal to f1 – f2 x n, where n is the mathematical integer closest to the exact mathematical value of the quotient f1/f2, and if two mathematical integers are equally close to f1/f2, then n is the integer that is even.
Note :

  • If the remainder is zero, its sign is the same as the sign of the first argument.
  • If either argument is NaN, or the first argument is infinite, or the second argument is positive zero or negative zero, then the result is NaN.
  • If the first argument is finite and the second argument is infinite, then the result is the same as the first argument.

Syntax:

public static double IEEEremainder(double dividend, double divisor)
Parameter:
dividend : the dividend.
divisor : the divisor.
Return :
This method returns the remainder when dividend is divided by divisor.

Example 1: To show working of java.lang.Math.IEEEremainder() method.

// Java program to demonstrate working
// of java.lang.Math.IEEEremainder() method
import java.lang.Math;
  
class Gfg {
  
    // driver code
    public static void main(String args[])
    {
        double did1 = 31.34;
        double dis1 = 2.2;
        System.out.println(Math.IEEEremainder(did1, dis1));
  
        double did2 = -21.0;
        double dis2 = 7.0;
  
        // Sign of did2 is negative, Output is negative zero
        System.out.println(Math.IEEEremainder(did2, dis2));
  
        double did3 = 1.0 / 0;
        double dis3 = 0.0;
  
        // First argument is infinity and Second argument is zero
        // Output NaN
        System.out.println(Math.IEEEremainder(did3, dis3));
  
        double did4 = -2.34;
        double dis4 = 1.0 / 0;
  
        // First argument finite and Second argument is infinity
        // Output first argument
        System.out.println(Math.IEEEremainder(did4, dis4));
    }
}

Output:

0.5399999999999974
-0.0
NaN
-2.34
