<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Hello all:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Does anyone have had problems with field calculations using the division operator?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Simple operations like:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">"HC01_VC04" / "HC01_VC03" * 100<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Do not work.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">The only workaround I found was to put the function abs into the denominator:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">"HC01_VC04" / abs("HC01_VC03") * 100<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Then it gives the result but this should be avoidable.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">I’ll send the table used if anyone want to try it.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue">Qgis version is 2.4 (32bit) under WIN7.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:Consolas;color:blue"><o:p> </o:p></span></p>
