It is not "false" but it is unnecessary to write that since . In some situations, adding a value for a variable can be viewed as an error. I was just pointing that out.

But this is trivial, so I wonder what did you really mean...
OMG enormous mistake from me, I thought from the start you had written . My mistake ! Then yes the statement is clearly wrong. It seemed so obvious, I must've been confused
EDIT : haha Archie Meade fell in the same booby trap
That's what I thought too, it seemed such a typical question that I just flew over it, now hopefully he made a typo
Pretty confusing stuff: what did the OP really mean?
I hereby propose to let the OP to correct his/her own post if he wants some attention: it's the minimum one must require from someone asking for help, namely to post CORRECTLY the question.
