Dear P45cal your direct result formula does not decrease the duration of the calculation.
Dear Fjns, I'm VERY SORRY, … to make the sample for you as simple as possible I set up a "2-digit-sized-values array" …
hoping to get a solution for "any digit sized values array" …
As a matter of fact my application happens to deal with a 4-digit-values array as well as a 6-digit-values arrays …
so in this case your solution, limited to a 99 lines help-column, does not seem to work for the 4 and 6 digit values … attached the real type array. AP
