The Nineteenth Byte

12:00 AM

Just read "I'm not a computer". I'd have my doubts about that.

There's no rush. One thing to check is should factorial base units be at the 0! or1! place - I have them at 1!, so always a trailing zero (but converting from it uses either, or both)

Dennis

It doesn't seem to follow Jelly's naming convention, but f and p don't exist with a dot below...

In order to get the same probability distribution as 2d6, you either have to use 2d6 or 2dSicherman

you always know by the lowest value in the distribution how many dice there are

@JonathanAllan That won't accomplish much. Jelly's character type uses Python's singleton strings. All instances of strin Jelly have length 1.

There is no next character. The string “abc” is represented as ['a', 'b', 'c'] internally.

@ASCII-only I'd apply the even/odd-rule to this. int+int and str+str give int, int+str and str+int gives str. That way, operations still cancel out like they should, e.g., 'a'+1` gives 'b', 'b'-'a' gives 1.

Wait, what's the kangaroo problem?

Q: Compute the kangaroo sequence

Backstory Disclaimer: May contain made up information about kangaroos. Kangaroos traverse several stages of development. As they grow older and stronger, they can jump higher and longer, and they can jump more times before they get hungry. In stage 1, the kangaroo is very little and cannot jum...

@Downgoat I don't think we have a default for that. It's up to the challenge author.

@Downgoat The vast majority of SE sites are blue, so the vast majority of chat rooms is usually blue. It's not a TNB thing at all. PPCG is also blue.

@EriktheGolfer -1 for spoiling joke

Erik the Golfer

Qwerp-Derp

Should I post the formula in my answer?

Crap got ninja'd

Erik the Golfer

@Qwerp-Derp Meh, I don't need it anymore, I posted my answer.

miles
