            Calculation when number is 999999999999999
            Asked 2021-Sep-06 at 12:33

            After I read #magically-increasing-numbers,

            so I was wondering about If made calculator with JS how and user put a large number like 9999999999999999

            As you already discovered, you ran into an issue with the limited precision of floating point numbers, since your number is outside of the range of "safe integers" which are stored with full precision (it is larger than Number.MAX_SAFE_INTEGER = 2^53 - 1).

            If you only need integers, the native BigInt type will work just fine (as long as you take care of converting things to/from a BigInt in the right way):



            Numbers with (.0) decimals are considered integers in Javascript?

            I was working with some validation that it was supposed to allow integers only, I had something like this:

            The Javascript standard is actually very clear about the difference between "mathematical values" and Numbers as represented in the language (

            From the mathematical standpoint, 100.0 is definitely an integer. From the JS standpoint, isInteger(100.0) is true, because isInteger is defined to return true for Numbers whose mathematical value is integer.

            Your uncertainty comes from the fact in some other languages 100 and 100.0 are indeed quite different things, with different storage mechanisms and the nature of operations performed on them. In Javascript, we actually don't know how a particular number is stored, and have no control over that. The standard says that all Numbers should behave as if they all were IEEE 754-2019 double values, but what sequence of operations a particular engine actually performs when you compute 1+2 and how they are different from 1.2+3.4 is up to that engine.
