Re: PARI-GP, Online WebAssembly version

Thanks, Bill... I was using a slow connection at the time, so the 12MB of the _javascript_ file (gp-sta.js) was taking too long to load, and perhaps failing to complete the download.

Now I'm trying on a faster connection so it works fine. And once it is cached properly in the browser, the connection speed is not an issue either.

Thanks again.

Just wait a bit and click on "Evaluate" again.

This webpage is loading the PARI/GP wasm binary in the background.
If you click on Evaluate before the binary has finised downloading,
it does nothing.
All the versions have this problem.

The speed is similar, but wasm has a better memory model, so you do not
need to allocate all the memory you need at startup.
