javascript bigint max value

JavaScript 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:

let x = 999999999999999;
let y = 9999999999999999;

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. Continue reading JavaScript BigInt
