Unless someone's cracked my password, the moderator has deleted the messages that I previously posted to this thread.
The deletions have been done without any notification and without providing any reason.
If the moderator is responsible, then I think it is a very ill-mannered way to behave.
If the moderator sees fit to delete this message also, I would hope that he will do so with more courtesy than the last time.
Naturally, I withdraw all criticism if he was not the one who deleted my posts, or he did so in error.
I will repeat the gist of the last post I made :-
You said that your number (assumed to be in A1) is always negative.
Therefore, using = -A1 will convert the number in A1 to a positive value (since 2 negatives equal a positive!).
It does the same as the other solutions that you seem to be happy with =(A1*-1), =ABS(A1), and it's a bit shorter.
