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+C  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: correct: A+B; incorrect: newfile = A+B. Use
       no spaces or blanks.

       Expert mode runs r.mapcalc for more complex expressions.
