While recently writing an AutoLISP routine, I had tried to retrieve the
value of the SYS VAR "LUPREC". I had the units set to Architectural with
the smallest denominator of 16. The value for "LUPREC" that I expected was
of course 16. The value that I got was 4, indicating Decimal units to 4
places. Changing UNITS to Decimal to 6 places produced a value for
"LUPREC" OF 6. My question is, is this a glitch or am I doing something
wrong.
