Java Math IEEEremainder() Method

The IEEEremainder() method of Math class calculates the remainder as prescribed by the IEEE₇₅₄ standard. This method simply returns the remainder when f1 (dividend) is divided by f2 (divisor).

Syntax:

public static double IEEEremainder (double f1, double f2)

Parameters:

The parameters ‘f1’ and ‘f2’ represent the dividend and the divisor.

Return Value:

The IEEEremainder () method returns the remainder when first argument is divided by second argument.

Special cases of the IEEEremainder() method are as follows:

• It returns the result same as the first argument, if the second argument is infinite.
• It returns NaN , if either argument is NaN or first argument is infinite or second argument is positive or zero.

Example 1:

public class JavaMathIEEEremainderExample1 {
    public static void main(String[] args) {
        double a = 40;
        double b = 12;
        //returns the remainder when a is divided by b
        System.out.println("Remainder : "+Math.IEEEremainder(a,b));
    }
}

Output:

Remainder : 4.0

Example 2:

public class JavaMathIEEEremainderExample2 {
    public static void main(String[] args) {
        double a = 40;
        double b = 2/0.0d;
        //returns the result same as the first argument, if the second argument is infinite
        System.out.println("Remainder : "+Math.IEEEremainder(a,b));
    }
}

Output:

Remainder : 40.0

Example 3:

public class JavaMathIEEEremainderExample3 {
    public static void main(String[] args) {
        double a = 0.0d/0.0d;
        double b = 2/0.0d;
        //It returns NaN , if either argument is NaN
        System.out.println("Remainder : "+Math.IEEEremainder(a,b));
    }
}

Output:

Remainder : NaN

Example 4:

public class JavaMathIEEEremainderExample4 {
    public static void main(String[] args) {
        double a = 45;
        double b = 0.0d;
        //It returns NaN , if second argument is zero
        System.out.println("Remainder : "+Math.IEEEremainder(a,b));
    }
}

Output:

Remainder : NaN
