 The round() function in r.mapcalc always returns an integer, regardless of
 its argument types. Integers are always 32-bit, so the result is limited
 to the range +/- 2147483647 (2^31-1).

 Suggestion: extend the function to allow to round numbers outside the
 integer range, and to round with a specific number of decimal places, like
 e.g., the function round() in R.

 Various options have been discussed on the mailing list, see this
