Does javascript have a remainder function?

Javascript does not have a remainder function. In JavaScript, the remainder operation is implemented using the modulo operator "%". The syntax is "value 1% value 2", and the return value is the remainder sought; the "%" modulo operator mainly operates on integers, but Also applies to floating point numbers, such as "3.1 % 2.3".

There is no remainder function in JavaScript, but the modulus operator "%" can be used to implement the remainder operation.

In JavaScript, the modulo operator "%", also known as the remainder operator, can perform division operations and obtain the remainder.

Syntax:

数值1 % 数值2

Example:

console.log(5 % 2);  //返回余数1

## Modulo arithmetic mainly operates on integers, but also applies to floating point numbers. For example:

console.log(3.1 % 2.3);  //返回余数0.8000000000000003

The value of the modular operation is consistent with the sign of the dividend.

console.log(-13 % 5);
// 返回余数 -3

console.log(4 % -2);
// 返回余数 0

console.log(-4 % 2);
// 返回余数 -0
