Hello all

I have a little trouble.. I need sign invert, but not work.. :(

I do :

<MvASSIGN NAME = "l.neg" VALUE = "{ -10}">
<MvASSIGN NAME = "l.pos" VALUE = "{ 10}">
<MvASSIGN NAME = "l.var" VALUE = "{ neg * -1}">

&[var]

10 - OK

now I need save diference

<MvASSIGN NAME= "alias.d.FIELD" VALUE="{ var - pos}">

In a database save -0

???

What I do wrong?

sign invert

Other than the fact you switch variable names (scoped vs.
non-scoped) I'm not sure what you think is wrong.

l.neg = -10
l.pos = 10

l.var = l.neg * -1 = -10 * -1 = 10

alias.d.field = l.var - l.pos = 10 - 10 = 0

Therefore alias.d.field stores zero, which is correct.

Roberto,
I've ran into -0 also, and I think it might be a flaw in empressa in how =
it
handles such situations. I had to check the variable for the existence =
of -0
and change it to just 0 manually.

sign invert

Ivo

(I use miva empresa)

I try it before and do the same "-0"

The procedure is one balance account

old balance, debit, credit and new balance

I think the trouble will be a var declaration but
when the balance is positive save good...
but if the balance is 0 save -0

If I var declare different when the balance is positive save negative, bu=
t
when the balance is 0 save 0..

:oS

sign invert

There are rounding bugs in diverse Empresa engines - surprisingly there =
are
often small rest numbers even after simplest integer operations, and
although mostly not displayed, they can completely break the result. =
Check
the list archive for [mvm:bug] or "bug" in subject. You can get rid of =
it
either by rounding, or sometimes by multiplying. For example

(-1*neg) ROUND 0
int(-1*neg)
floor(-1*neg)
1*(-1*neg)

You have to see what will work the best in your situation. Upgrading =
your
Empresa or Mia would be a good precaution.
