I didn't know that operator, thanks!

But I was not clear, as I was looking more towards a lowlevel function.
E.g. "trunc", "floor", "ceiling", ... are defined in names.c and while
I currently not fully understand this I thought there could be a
similair thing for fraction.

I defined the function "frac <- function(x) abs( x - trunc(x) )"
which seems to work well.

Thanks again,
Hans-Peter
