Anyway, here is my minifier for JavaScript numeric literals, I hope it is of use to youhttps://github.com/ferno/minify-numeric-literal …

An earlier version of UglifyJS naively replaced `Infinity` with `1/0`, but that turned e.g. `x/Infinity` into `x/1/0`
It also replaced `NaN` with `0/0`, turning `x/NaN` (always `NaN`) into `x/0/0` (`Infinity`, `-Infinity`, `NaN`) and SAVING NO CHARACTERS

`1<<17` is shorter than `131072`. `~99` is shorter than `-100`. `1e9-7` is shorter than `999999993`. But when is such a substitution safe?
-
And it turns out the number crunching to determine the shortest possible expression of an arbitrary float is deep and complicated

I seem to remember `NaN` not being a value in older browsers (only output, not input).

I know of no environment where the `NaN` global is missing, but I suspect that it, like `undefined`, may once have been reassignable
