RE: Negative numbers problem

I think it really depends on context.... If this is a Credits file, then I would store values as a positive, then use it as Allowance - Credit. (Debit memo would store negative values in the Credits file.) If this is an AR transaction file, I'd store the value as negative, so that summing rows results in actual net....

Hi Adam

So many options...

Eval Available = Allowance + Credit
Eval Available = Allowance - %Abs(Credit)
Eval Available = Allowance - (Credit * -1)

Personally I would store the value as positive and subtract it directly. If
the value was then negative for any reason it would imply the reverse.

I have a field which is a credit amount so it has the negative sign. I have
to subtract this from the Allowance account amount, to show the user how
much is left in the account. I am getting that it adds it bec. negative
minus negative. What sort of techniques are best to use? I can simply
declare it to be pos. in the first place i suppose.
