      The min/max ones are entirely sensible if you think about it, and the float addition inaccuracy is expected in pretty much every popular programming language. The others, though, yeah. JS WTFs.

      The float problem is that in JS there is no non-float alternative

      Few programming languages have a decimal type built in as a core datatype. The float problem where 0.1 + 0.2 != 0.3 is not unique to JS. The problem with *ints* being all fucked up (in strange ways beyond IEEE754) when you exceed the precision of double *is* unique to JS.

          More on just how broken JS is with float integer representations. It's not just about loss of precision, toString is broken too.https://twitter.com/marcan42/status/1008999468492918784?s=19 …

          Yet another JS WTF. JS uses 64-bit floats for numbers, but it *lies* when displaying them. 0x4000000000000000 is 4611686018427387904 and is *perfectly* represented as a float. But JS renders it as 4611686018427388000, because that has fewer significant digits in decimal?! pic.twitter.com/xbYbqMP9mY
