Modulus (%) operator returns only the remainder. etc. The sign of the value returned by a modulo operation is determined by the sign of the dividend. Pythonâs % operator is a modulo operator. One arithmetic operator that is slightly less familiar is the modulo (sometimes known as modulus) operator, which calculates the remainder of a quotient after division. Incrementing. When working with many javaScript projects the use of modulo comes up from time to time. This gives us the reminder after a division. If the divisor is an infinite number, the result is the dividend.

The operators are for addition, subtraction, multiplication, division and remainder (or modulo), respectively. One arithmetic operator that is slightly less familiar is the modulo (sometimes known as modulus) operator, which calculates the remainder of a quotient after division. So, basically, modulo does integer division and then gives back whatever is left from the dividend. Javascript  If Statement opposite of Modulus Division..? The modulo operator is used to find whether a given number is even or odd. In JavaScript, array is a single variable that is used to store different elements. Hint: There is a handy decrement) operator that is a great shortcut when youâre subtracting numbers by 1. would result in the remainder of 2 being stored in the variable resultOfMod.

To obtain a modulo in JavaScript, in … We also have thousands of freeCodeCamp study groups around the world. For positive values, the two are equivalent, but when the dividend and divisor are of different signs, they give different results. However, a true modulus operator would always return a positive value, so 21 modulo 5 would equal 4. If you want to read more about remainder and modulo: The Wikipedia page on âmodulo operationâ has much information.
