Not entirely unreasonable as all `number`s are floats by default in JS, but the implementation of the entire package (https://github.com/nefe/number-precision/blob/master/src/ind...) is less than 100 lines of code and actually contains a method called "minus".
The very worst JS packages I've seen have got to be is-odd and is-even. 430,796 and 202,268 downloads every week, I kid you not!
