So, for parseInt('10152547376283911', 10) I'm expecting 10152547376283911, but I'm getting 10152547376283912.

    Your number is outside of the range of ints that can be accurately expressed as a floating point number

Javascript native numbers do not have enough precision (significant digits) to hold the number you are expecting. See the question What JavaScript library can I use to manipulate big integers? for suggestions on how to deal with this problem.



Depending on your application, you may actually be able to use strings instead of numbers (for example, if your number represents something like a physical part number). You would only need a bigint library if you intend to do arithmetic on your numbers.

            What visual should I use to simply compare current year value vs last year in Power BI desktop

            Image
            0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
