Javascript fudges numbers??? I don't see how making stuff up is helpfull.

The README contains over 8900 lines of 200+ well documented standalone examples with many many code samples comparing JS and R side by side for every function call.

THE RESULTS ARE EXACTLY THE SAME!!

You took the effort to throw dirt at JS, but could you not have glossed over the "proof" first?

You seem to not know that IEEE floating is a standard, I suggest you read up on that first
