Integer Division in Java

In this tutorial, we will learn about integer division in Java. Let’s say we have two variables of integer type a=25 and b=5 and we want to perform division.

When it comes to a decision of maintaining precision or avoiding precision mainly at the time of division because while doing division there are high chances of losing precision.

Example of simple division

In the given example we have three int type variables a , b , c and we are storing division of a & b into c . We recommend you to run this example and observe the output and match your observations with whatever we discussed below.

In the above case, the division will work finely because all the variables are in the form of an integer and 5 divide 25 completely. Think about 10/3 definitely c cannot store 3.3333. as it is an int type of a variable and able to store integer data only and it will hold just 3 . In the below case it is not considering a reminder.

Example: losing data

Here, we are dividing two integers and storing the result into int that leads to loss of data because integer does not hold decimal place values.

Now let’s bring the idea of doing real division where we will store the value in double.

Example

In the code given below, to observe the output of what happens when we change the datatype of variables from float to int and vice versa. You will get integers or real numbers.

Conclusion:

After implementing all the above codes we can conclude some important observation based on the datatype of divisor and dividend

There are two types of division in Java—integer division and floating-point division. Both types use the forward slash (/) symbol as the operator, following the format dividend / divisor. Read on to learn how to divide two integers (non-decimal whole numbers) to receive an integer quotient, and how to use floating point division to get a decimal result.

Integer Division

When you divide two integers in Java, the fractional part (the remainder) is thrown away. For example, if you were to divide 7 by 3 on paper, you’d get 2 with a remainder of 1. But when you divide two integers in Java, the remainder will be removed and the answer will just be 2. [1] X Research source To use integer division, you’d use this syntax:

int a = 7; int b = 3; int result = a / b; // result will be 2 

• Dividing two integers always results in an integer. If you want to get a decimal result from dividing two integers, use floating point division.
• If you try to divide an integer by 0 using integer division, you’ll get an ArithmeticException error at runtime, even if the program compiles fine. [2] X Research source

Floating point division

If either operand in the equation is of the float or double type, you’ll need to use float division. You can also use float division if you are dividing two numbers and want a decimal result. To use this division type, set the dividend and divisor to a float. [3] X Research source With our example of 7 divided by 3, our code would look like this:

float a = 7.0f; float b = 3.0f; int result = a / b; // result will be 2.33 

• When dividing by zero with floating point division, the result will be NaN (Not a Number). [4] X Research source

Expert Q&A

When dividing mixed integer and floating point numbers, the floating point values (float or double) are automatically converted to the double type when dividing.

Java 8 program for the division of two numbers

In this example, we will see “How to perform division of two numbers in Java 8?”. To achieve that, we are going to use BiFunction interface introduced in Java 8 as part of the functional interfaces and we will see it through several different ways.

Example 1. Java 8 code for division of two integer numbers (hard-coded integers)

System . out . println ( «Division of Two Numbers using BiFunction Interface — ‘apply’ example \n» ) ;

System . out . println ( «Division of 2 integer values — » + number1 + » and » + number2 + » is: » + biFunctionObj . apply ( number1 , number2 ) ) ;

Example 2. Java 8 code for division of two integer numbers (scanner input)

System . out . println ( «Division of Two Numbers using BiFunction Interface — ‘apply’ example \n» ) ;

System . out . println ( «\nDivision of 2 integer values — » + n1 + » by » + n2 + » is: » + biFunctionObj . apply ( n1 , n2 ) ) ;

Example 3. Java 8 code for division of two double numbers (scanner input)

System . out . println ( «Division of Two Double Numbers using BiFunction Interface — ‘apply’ example \n» ) ;

System . out . println ( «\nDivision of 2 double values — » + n1 + » by » + n2 + » is: » + biFunctionObj . apply ( n1 , n2 ) ) ;

Divide two numbers without using Arithmetic operator in Java

Divide two numbers without using Arithmetic operator in Java

In this tutorial, we will discuss the concept of Divide two numbers without using Arithmetic operator in Java

In this topic, we are going to learn how to divide two numbers without using Arithmetic operator in Java language

What is division

The division is a method of splitting a group of things into equal parts. The division is an arithmetic operation inverse of multiplication

It is one of the four basic operation of arithmetic calculation others being addition,subtraction,multiplication

The division of two natural numbers means it is the operation of calculating the number of times one number is contained within one another

Java exercise to Divide two numbers

Program to division of two numbers without division operator

The program allows the user to enter two integer numbers and then it calculates the division of the given numbers without using the division operator in Java language

import java.util.Scanner; class Divisionwithoutdivope2< public static void main(String args[])=num2) < num1=num1-num2; result++; >System.out.println("Division is:"+result); > >

When the above code is executed, it produces the following result

Enter the value to num1: 500 Enter the value to num2: 25 Division is: 20

Program to division of two numbers using Bitwise operator

The program allows the user to enter two integer numbers and then it calculates the division of the given numbers using with the Bitwise operator in Java language

import java.util.Scanner; class DivisionwithBitwise < public static void main(String args[])while(temp>1) < num2>>=1; temp>>=1; if(num1>=num2) < num1-=num2; result+=temp; >> System.out.println("Division is:"+result); > >

When the above code is executed, it produces the following result

Enter the value to num1: 650 Enter the value to num2: 25 Division is: 26
