Javascript console.log huge number

Question

In javascript, why

console.log(99999999999999999)

results to

100000000000000000

TIA

See [MAX_SAFE_INTEGER](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER) which you exceed. — Alex K., Feb 07 '18 at 14:59

Because your number is too large for javascript.

See here the Number.MAX_SAFE_INTEGER constant

Javascript can't handle number over 2^53 - 1 without rounding errors

I suggest you use Strings for big numbers
