Yes thanks: the 2nd is the simplest way to do what I want.

Thanks too, but that's not what I wanted: it's not for printing,
but simply to limit the display to eg  4  decimal places, not  16 ;
the calculations still wb as accurate, but the output easier to read.
Is that possible with Python ? -- ie a setting in  ascript.py 
to tell Python to display only the 1st  4  places in all output
without any further input from the user when doing the calculations;
presumably it wb a command s/he could enter when in interactive mode too.
