Performs arithmetic operation over raster data.
The expression (arithmetic stringIt) must be formed by a combination of the following elements, separated by spaces:
Operators: +, -, *, /
Real Numbers (negative numbers must follow the form "-1.0")
Raster bands: R0:1, R0:1, R1:0, .... (R0:1 is a reference to the first raster - with index 0 - from feeder, second band - with index 1).
