[q] floating-point number?

[Janusz Michalak]

Hello Sungwon,

On my knowledge, to convert 'integer_raster' to 'fp_raster'
you need enter:

r.mapcalc 'fp_raster'='integer_raster'*1.
                                        ^
                                        this dot is a key in this problem
Good luck.
