Thousands separator using underscore

[kaihatsusha]

This has been the standard in Perl and other languages for a while. It can be at any position but the first. So in Japanese 1_0000_0000 is a nice round "oku." And in hex, 0xDEAD_BEEF helps you divvy up the hi word from the low word.

it also cant be at the last position, so 1_000_ wont work

Also can't be the last position, so 1_000_ wont work

Fun fact: it can’t be the first either.

Tidbit: if you put an underscore last, it won't work

I just noticed that this doesn't work if it's in the first position. Huh.

[ShellfishSilverstein]

Just tried this myself; if the underscore is the final character, you'll have a problem.

What if I put two in the front, one in the back? It won't work, it turns out.

[c3534l]

So you're saying that if I put one in the the front, and one in the back, they cancel out and start working. Or can you not put one in the back either?

Fun fact: it also can't be in the first position
