Dear all,

Just a little comment on Math Formula modul.

I have a Double column with some zeros and some other numbers in rows. I'm using Math formula to negate these numbers, like: `-1*$myDoubleColumn$`

. On rows with zero the result is -0.

Finally i'm using `(-1*$myDoubleColumn$)+1-1`

which gives me the correct value, 0, but it tells me there is something internally wrong with Math Formula modul.

What do you think?
