Java IEEEremainder Function

by

The Java IEEEremainder Function is one of the Java Math Library functions, and it is useful to find the remainder of the two arguments as prescribed by the IEEE 754 standard.

In this article, we will show how to write Math.IEEEremainder function in Java Programming language with example.

Java IEEEremainder Function syntax

The basic syntax of the Math.IEEEremainder Function in Java Programming language is as shown below:

static double IEEEremainder(double x, double y); // Return Type is Double

//In order to use in Java program use following code
Math.IEEEremainder(double x, double y);
  • x: Please specify the dividend value here.
  • y: Please specify the divisor value or power here.

The Java Math.IEEEremainder function will find the remainder of the two arguments. The remainder value is mathematically equal to x – y × n, where n is the integer closest to the exact mathematical value of the quotient x / y. If two integers are equally close to x / y, then n is the integer that is even.

There are some special cases where the result of the Java IEEEremainder will be different, and they are:

  • If the first argument is infinite, Math.IEEEremainder will return the result as NaN.
  • If the second argument is positive or negative zero, Java IEEEremainder will return NaN.
  • When either the x or y argument is not a Number, Java Math, Ieeeremainder will return the result as NaN.
  • If the first argument is finite and the second argument is infinity, then Math.IEEEremainder will return the first argument value as a result.

The return value is nothing but x Modulus y, and if you find it difficult to understand the modulus operator. For example, 6 % 12 = 2.

Java IEEEremainder Function Example

The Java Math.IEEEremainder function returns the remainder of the given number. In this Java example, We are going to find the remainder of both positive and negative double values and display the output.

//Java Math.IEEEremainder Function

package MathFunctions;

public class IEEEremainderMethod {
	public static void main(String[] args) {
		 // get the remainder when x/y -- Mod
		double a = Math.IEEEremainder((5.12 - 4.65 + 3.53), 3);
		System.out.println("Math.IEEEremainder Result = = " + a);	
		
		System.out.println("\nMath.IEEEremainder Result for Zero as First argument = " + Math.IEEEremainder(0, 2));
		System.out.println("Math.IEEEremainder Result for Zero as Second argument = " + Math.IEEEremainder(2, 0));

		System.out.println("\nMath.IEEEremainder Result of Positive Number = " + Math.IEEEremainder(9, 8));
		System.out.println("Math.IEEEremainder Result of Positive Number = " + Math.IEEEremainder(6, 12));
		
		System.out.println("\nMath.IEEEremainder Result of Negative Number = " + Math.IEEEremainder(-98, 6));
		System.out.println("Math.IEEEremainder Result of Negative Number = " + Math.IEEEremainder(164, -5));
	}
}

ANALYSIS

Within this IEEEremainder function example, First, We declared variable a of type Double. Please visit Java Arithmetic Operators article

Next, we used Java Math.IEEEremainder functions directly on expression. Here, we used System.out.println statement to print the result as output.

double a = Math.IEEEremainder((5.12 - 4.65 + 3.53), 3);
System.out.println("Math.IEEEremainder Result = = " + a);

From the above statement, Math.IEEEremainder((5.12 – 4.65 + 3.53), 3) ==> Math.IEEEremainder(4, 3) ==> 0.99 (~ 1)

Next, We used IEEEremainder Function with one positive double value and another argument as zero.

System.out.println("\nMath.IEEEremainder Result for Zero as First argument = " + Math.IEEEremainder(0, 2));
System.out.println("Math.IEEEremainder Result for Zero as Second argument = " + Math.IEEEremainder(2, 0));

Here, We used the Java IEEEremainder Function directly on Positive double values.

System.out.println("\nMath.IEEEremainder Result of Positive Number = " + Math.IEEEremainder(9, 8));
System.out.println("Math.IEEEremainder Result of Positive Number = " + Math.IEEEremainder(6, 12));

Next, We used Math.IEEEremainder Function directly on Negative double values.

System.out.println("\nMath.IEEEremainder Result of Negative Number = " + Math.IEEEremainder(-98, 6));
System.out.println("Math.IEEEremainder Result of Negative Number = " + Math.IEEEremainder(164, -5));
