How can I get the charcode from the char? Like the reverse of char_generate.

tex.stackexchange.com/questions/277876/… --

That one doesn't work with a char stored in a variable for example.

Although there are function to compare a char with a char code

@user202729 use the backtick `a is the character code of a

> That one doesn't work with a char stored in a variable for example.

I tried.

\def\x #1{`#1}

\x a

It just result in `a

Actually it's just for debugging, so printing to a file is an option

But still, how to do it?

@user202729 you need it o in the context of a <number> so \number`#1 for example.

Okay

I see

I didn't know how it works initially, so I find it a little weird that it doesn't have a special character code

if the character might be active safer to do \number\expandafter`\string#1

@user202729 what doesn't have a special character code?

1:21 PM

I mean, originally I thought if `a is handled specially by the TeX engine to expand to the number 97 or something similar, it should have a category code for the left quote

In reality, it's handled by \number and the left quote is just a normal category 12 character

@user202729 well it's same as all literal number syntax, digits have to be catcode 11 or 12 (including A-F for hex digits) hex needs a catcode 12 " at the start, octal needs a catcode ' at the start and numbers given by characters need a catcode 12 `

compare "10 which just prints "10 and \number"10 which prints 16

@user202729 just in time, sensible hex answer...

I am wondering can anyone please help with this question: tex.stackexchange.com/questions/618382/…

4:15 PM

why use the algorithm environment hacked like `\renewcommand{\thealgorithm}{1}
\addtocounter{algorithm}{-1}
\floatname{algorithm}{Code}` ? just use the float package and define yourself a new float type \newfoloat{code} or whatever you want to call it

Do you have an example?
