JavaScript BigInt - w3Schools - Chapter 23

JavaScript BigInt avaScript BigInt variables are used to store big integer values that are too big to be represented by a normal JavaScript Number. JavaScript Integer Accuracy JavaScript integers are only accurate up to 15 digits. In JavaScript, all numbers are stored in a 64-bit floating-point format (IEEE 754 standard). With this standard, large integer cannot be exactly represented and will be rounded. Because of this, JavaScript can only safely represent integers: Up to 9007199254740991 +(253-1) and Down to -9007199254740991 -(253-1). Integer values outside this range lose precision. How to Create a BigInt To create a BigInt, append n to the end of an integer or call BigInt() BigInt: A new JavaScript Datatype The JavaScript typeof a BigInt is "bigint" BigInt is the second numeric data type in JavaScript (after Number). With BigInt the total number of supported data types in JavaScript is 8: BigInt Boolean Null Number Object String Symbol Undefined BigInt Operators Operators that can be used on a JavaScript Number can also be used on a BigInt. Arithmetic between a BigInt and a Number is not allowed (type conversion lose information). BigInt Decimals A BigInt can not have decimals.
