The Modulo Operator in Java

Let us check some use cases: Checking if a number is even or odd: package com. Well, the answer to that is 3. Examples might be simplified to improve reading and basic understanding. Instead of returning the result of the division, the modulo operation returns the whole number remainder. The unary plus operator returns the value of its operand. If either or both operands of the mod operator have type double, then evaluating it produces the remainder.

This technique is often used to alternate values within a loop. This kind of mod operator does not exist in C or C++ where the mod operator only works with int operands. The highest possible amount of whole 3 meter shelves is three.

The remainder is computed by assuming the division yields an integer result, with the rest being a remainder How to use Modulo Operator in Java with Example You cannot understand anything better without any example.

The % operator returns the remainder of two numbers. The result should be the remainder that would remain if we had divided the first number by the divisor. It divides left operand with the right operand and assign the result to left operand. Keep in mind that time is also, in effect, a long running loop. I am sure you would be familiar with the term Modulus. Again, examples might help clarify this idea; in each instance here, the divisor is 5, so results will range from 0 - 4. Of course, both values can also be double, so 6.

It is denoted by % percentage sign. The Bitwise Operators Java defines several bitwise operators, which can be applied to the integer types, long, int, short, char, and byte. Four shelves would result in 12 meters of total shelves, and that is too much. Same is true for modulo operator in Java. It adds right operand to the left operand and assign the result to left operand.

Modulus in Java: Syntax X%Y Where X is the dividend and Y is divisor. If this seems strange, boring, or not particularly useful, bear with me a bit longer - or just skip ahead to the. The left operands value is moved right by the number of bits specified by the right operand. Due to the same reason a division by zero isn't possible, it's not possible to use the modulo operator when the right-side argument is zero. Use to reverses the logical state of its operand. If i had a wall that was 11 meters wide, and shelves that were 3 meters each, how many shelves can i fit? For example, if we wanted to know the number of hours in 349 minutes, having the result expressed as 5 hours 49 minutes may be more helpful than 5. For example, in many cases like or , you can use modulus operator with 10 to get the last digit, for example, 101%10 will return 1 or 1234%10 will return 4, the last digit.

Staying with the shelves, how many meters are the th. You use the modulo operator to get the remainder of the division between an int variable and 10 and a double variable and 10, as described in the code snippet below. For example, to find out if a number is a prime number, or in an accounting application that is used to calculate money installments and remaining amounts. Use Cases for the Modulo Operation When I first encountered the it, the modulus operator seemed little more than a bit of mathematical trivia. The modulo operator is used to compute the remainder of an integer division that otherwise lost.
