Joseph,

To see what I am saying try this one;

SET DECIMAL TO 1
lnVar1 = 44/7
? lnVar1 && 6.3
SET DECIMAL TO 2
lnVar2 = lnVar1 * 1
?lnVar2
disp memo like ln*

Pay carefull attention to the two values that display memo shows you, one is formatted to the decimal setting and the other is the actual value in memory.

What we are seeing here is the very reason that I NEVER use SET DECIMALS. When I need a specific decimal precision I use the ROUND() function to make it.
