What is the biggest number scratch can handle? Once the number is too big, scratch will start treating the numbers like infinity. I want to know at what point it will do that. Also at what point will scratch start using scientific notation?

Through testing, I've determined that the lowest integer represented using scientific notation appears to be 10^21.

Through some quick testing it looks like there isn't a direct cutoff for the maximum number, but rather that larger numbers seem to gradually get more buggy. I found that at around 2^1005, the display broke down and just showed 0. I also noticed that 1e308 + 1e307 resulted in approximately, 9.88e307, which is incorrect. The first *actual* instance of infinity (where an equals block determined that the variable was equal to Infinity) was at around 2^1024.

I would recommend trying to keep numbers below 1e300.

I did testing with variables. Like TechEpic, I also got that it starts using e notation around 10²¹

For me, it started displaying infinity at e302, which is a little bit below the 2^1024 that techepic got, which is about 1.8e309

Note that there's a discrepancy between when a variable's value overflows to Infinity vs when Infinity gets shown in the variable watcher.

As noted above, the variable watcher shows Infinity by about 1.8x10^302. However, the actual overflow only happens at about 1.8x10^308.

it just says infinity, if it gets too big for it to display.
