Phoronix: Firefox 68 Integrates BigInt Support

In addition to Firefox 68's WebRender slated to deliver much better performance, another headlining feature of this next Mozilla Firefox web-browser update is BigInt support...

can handle values up to 253

Eh, no. More like 2^53.

Larger than 2^53.. JS can already handle numbers up to 2^53.

Finally
this should have been done 10 years ago.

I turned on webrender on Firefox Nightly 69.0a1 tonight. Playing videos caused the CPU usage to basically double. I couldn't see any discernible difference in playback, so I turned it back off.

BigInt supports arbitrary-precision integers, so it can correctly do arithmetic on a 7000-digit number if you wanted.

So, for example, if you wanted to calculate 3 ** 50 % 81, you could do that using BigInt: 3n ** 50n % 81n == 0n (since 3 ** 50 is a multiple of 3 ** 4 or 81).
If you tried that using standard JavaScript numbers, it would give the wrong answer due to rounding: 3 ** 50 % 81 == 42

Obviously... why do you seem to think you're telling me something I don't know? The only reason I pointed out what I did was RealNC's response was rather incomplete/unclear.

additional elaboration for the benefit of others. It's obvious that you already know about BigInt, didn't mean to offend.

Firefox runs slower than Chrome/Chromium.
