Europeans! You use a comma for the decimal separator, like π = 3,14159... which is FINE.

But what do you do for functions of more than one variable?

Like: f(x,t) = t(1,23, 4,56) ???

@christianp I mean, in written text like emails or chat where typesetting isn't as critical, it's usually obvious what one means. If there is a space after a comma, it's not parts of the number. So you'd say something like: the lengths were 1,2, 3,0 and 3,3 metres (but in Swedish of course).

I've never written maths in LaTeX in Swedish, so I'm not sure how you'd do it there. There is a package called icomma that I see a university mention in their guide.

@christianp you have several alternatives: put decimal comas as ', use ; for separate arguments are the most common I Think

@christianp There is no standard, nor a best way. You can either use coma, prime, dot, semicolon, aesthetics (size, shape, space). If your text does not include to many occurrences, a good spacing is just fine.

@christianp I use currying on a regular basis, so often I just write "f(x)(t) = t(1,23)(4,56)".

However, as this is can be confusing for others unfamiliar with it, I would resort to either using semicolons as delimiters or using dots as decimal separators.
I'm starting to see the latter more and more, though.

@christianp see, that's why USSR had basically to give up on their efforts to design computers, and started stealing designs from Americans 😜
