[GRASS-dev] d.histogram and FP maps

[Martin Landa]

Hi all && Markus

I have added a new parameter 'ndigits' to the d.histogram module

[snip]

  ndigits   Number of digits after the decimal point (fp maps only)
            default: 1

I am waiting for your comments... Shall I commit the patch to CVS HEAD?

Best, Martin
