I would say (but without testing... I may be wrong) that this is slower than the one line formula. It has two lines of code instead of one and, in this case, I believe this make it slower even if you save in function calls.

Anyway, the performance is not so important. Except when you need to use such formulas for SQL statements, table scanning & other commands that must do a huge number of such calculations.
