@Satzz For that you can check out [How to deal with floating point number precision in JavaScript?](https://stackoverflow.com/questions/1458633/how-to-deal-with-floating-point-number-precision-in-javascript). – Ivar Aug 23 '18 at 14:03

@Satzz This is how math involving decimals works in virtually all programming languages, not just JavaScript. You need to round your numbers when you display them to the user, specifying the precision you want. – user229044 Aug 23 '18 at 14:14
