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 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.
