What Are 32-Bit Integers?

Problem

You want to be able to determine the difference between a 32-bit integer and another numeric value (such as the default number—64-bit floating point).

Solution

A 32-bit integer is vastly different from a variable bit floating-point number, which is the standard type of number in JavaScript. 32-bit integers can only be created using bitwise operators , which will be covered all throughout this chapter.

The Code
