DESCRIPTION

       r3.mapcalculator  provides  a  GUI  frontend  to r3.mapcalc.  Up to 5 maps can be combined
       using simple expressions.  In the  expert  mode,  it  runs  r3.mapcalc  for  more  complex
       expressions.  Enter an r3.mapcalc expression in the formula field using the format: A+C or
       exp(A+C)+(B-2)*7 where A, B, C are 3D raster volumes 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 r3.mapcalc for more complex expressions.
