Just for the record (and for the curious):
You can also always create your own decimal places. But you need pv's or globals for the interim results to avoid rounding errors.
number n = 23.452612
you want three decimal places
1) int/round/ceil/floor(n*1000); store the result in a variable v. [v = 23452 or 23453, depending on your rounding choice]
2) result = v / 1000 [result = 23.452 or 23.453, depending on your rounding choice]
