This is more of a theoretical question.

Is it possible to use ternary operators, like it is possible in C (e.g. (a<b) ? a : b), and if yes how?

  • Are you looking at using an input like \evaluate{a<b ? a : b}?

  • @Werner I'd appreciate an explanation on how this works. but I was more interested in how ternary operators can be used as a tool of programming.

Yes C only needs different syntax for ? and if because it distinguishes between statements and expressions. programming languages that don't make that distinction or don't make it so strongly, can naturally use the value of an if-expression.

so you do not have to go

\ifnum \count0<\count2

which is the analogue of a C if surrounding two assignments.

You can go

\count3=\ifnum \count0<\count2 4\else 5\fi

with the if expression providing the value of a single assignment which is the analogue of a C ternary expression.
