Hello all: Thanks Ralf. The columns used are integer. The resulting column is real, lenght=10 precision=1
Writing "HC01_VC04" / "HC01_VC03" * 100.0 Does not work either. Applying convert function toreal() to one of the columns, produces correct results. I checked it against LibreOffice Calc. BTW: The calculator has a strange behavior though. I need to sort and sort again the calculated column to 'refresh' the table values.

I've tried many times to update a new field using both the old field calculator and the new interface but they just don't work with division. Simple operations like: "HC01_VC04" / "HC01_VC03" * 100 Do not work. The only workaround I found was to put the function abs into the denominator: "HC01_VC04" / abs("HC01_VC03") * 100 Then it gives the result but this should be avoidable. I'll send the table used if anyone want to try it.
