Description

Processing allows to use an expression to calculate the value of a "number" entry. See http://docs.qgis.org/2.2/en/docs/user_manual/processing/toolbox.html#the-algorithm-dialog

When using a script or algorithm in "iterating" mode (green arrow next to one vector layer entry), it could be handy to be able to use one or more field names of this layer in the expression, so that the entry numbers or string can be calculated with an expression like

"somefield" * 2 + "otherfield"
