I downloaded a calculator script from highend3d...

http://www.highend3d.com/maya/downl...\_Calculator.mel

So guys, can someone please explain me these lines of code :

float $ris = eval ("float $dummy = " + textField -query -text $totale);
textField -edit -text $ris $totale;

Thanks for your time

this is the calculation, its the result of whatever you happen to have typed in the field (read docs about eval, its basicaly a just in time compile of the shard inside)

This sets the resuult back into the gui!
