Expression editor in Layer Properties does not support division of integer data

Original Redmine Issue: 11182
Affected QGIS version: 2.4.0
Redmine category:expressions

---

Affected function: under Layer Properties --> Style --> Graduated --> Expression

Issue: writing an expression that divides values in two separate columns (type: int; length: 10) of an ESRI SHP file results in incorrect value (0). Addition, subtraction, and multiplication all work as expected and produce sensible results.

Expected behaviour: when dividing two integer values, the result should be promoted to a real value.

The Expression editor is non-functional in its present state.

That's the intended behaviour. Division of integers produce integers. You can convert either argument using @to real(int)@ to produce a floating point result.
