Most people do not understand the knowledge points of this article "what the javascript residual function is", so the editor summarizes the following, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "what is the javascript residual function" article.

Javascript has no remainder function. In javascript, the remainder operator is implemented using the modular operator "%". The syntax is "numeric 1% numeric 2", and the return value is the remainder; the "%" modular operator operates mainly on integers, but also applies to floating-point numbers, such as "3.1% 2.3".

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

In javascript, the modular operator "%", also known as the remainder operator, can be divided and get the remainder.

Syntax:

Numerical value 1% numerical value 2

Example:

Console.log (5% 2); / / returns the remainder 1

Modular operations mainly operate on integers and are also suitable for floating-point numbers. For example:

Console.log (3.1% 2.3); / / returns the remainder 0.800000000003

The value of the modular operation is consistent with the symbol of the divisor.

Console.log (- 13% 5); / / return remainder-3console.log (4%-2); / / return remainder 0console.log (- 4% 2); / / return remainder-0
