Yep, that's how javascript works https://jsfiddle.net/tfrdn756/1/, this is related to floating point arithmetic https://en.wikipedia.org/wiki/Floating-point_arithmetic.

This calculator just run the operation with the javascript interpreter and there's no precise math operations or anything like that.
