Bing gives 1 though!

So duckduckgo uses the normal 64bit floating point, and the clever people at bing automatically switch to bignums when needed. But I have no idea what google does to get that 0?

I think Google is truncating the numbers. You get 0 even if you do:

9999999999999999 – 9999999999999990
