r.mapcalculator help
r.mapcalculator [-eo] [amap=string] [bmap=string] [cmap=string] [dmap=string] [emap=string] [fmap=string] formula=string outfile=string [help=string] [--overwrite] [--verbose] [--quiet]

Flags:

-e
Expert mode (enter a set of r.mapcalc expressions)
-o
Do not overwrite existing map
--overwrite
Allow output files to overwrite existing files
--verbose
Verbose module output
--quiet
Quiet module output

Parameters:

A
bmap=string
B
cmap=string
C
dmap=string
D
emap=string
E
fmap=string
F
formula=string
Formula (e.g. A-B or A*C+B)
outfile=string
Name for output raster map
help=string

Default: -

DESCRIPTION

r.mapcalculator provides a GUI frontend to r.mapcalc. Up to 5 maps can be combined using simple expressions. In the expert mode, it runs r.mapcalc for more complex expressions. Enter an r.mapcalc expression in the formula field using the format:
A+B or exp(A+C)+(B-2)*7 where A, B, C are raster maps entered in the A field, B field, and C field.

Do not enter output file in the formula field, hence:

The expert mode runs r.mapcalc for more complex expressions.

EXAMPLES

A+B

exp(A+C)+(B-2)*7
