# Question: How does integer division work in Java?

Contents

Java does integer division, which basically is the same as regular real division, but you throw away the remainder (or fraction). Thus, 7 / 3 is 2 with a remainder of 1. Throw away the remainder, and the result is 2. Integer division can come in very handy.

## Does integer division round up or down in Java?

The answer is Yes. Java does a round down in case of division of two integer numbers.

## How do you do division in Java?

Since most keyboards don’t have the times and division symbols you learned in grammar school, Java uses * to mean multiplication and / to mean division.

## What is the difference between division and integer division?

If one or two sides has a floating point number, then it means floating point division. The result of integer division is always an integer. Integer division determines how many times one integer goes into another. The remainder after integer division is simply dropped, no matter how big it is.

## What happens when you divide two integers in Java?

When dividing two integers, Java uses integer division. In integer division, the result is also an integer. The result is truncated (the fractional part is thrown away) and not rounded to the closest integer.

## Does INT division round up?

If the divisor and dividend have the same sign then the result is zero or positive. If the divisor and dividend have opposite signs then the result is zero or negative. If the division is inexact then the quotient is rounded up.

## Does integer round up or down?

INT rounds a number down using the Order rounding method. That is, it rounds a positive number down, towards zero, and a negative number down, away from zero. Therefore, it’s easy to use INT to round a number up using the Math method.

## How do you round a division in Java?

## What is integer math Java?

Java Integer Math

Math operations performed on Java integer types ( byte , short , int and long ) behaves slightly different from how normal math operations work. Since Java integer types cannot contain fractions, each calculation involving one or more integer types have all fractions in the result cut off.

## How do you divide negative numbers in Java?

If you divide a number by zero, and the signs of the numbers are different, the result is negative infinity. -40.0 divided by 0.0 is negative infinity, as is 34.0 divided by 0.0 .
