yet another solution that does exactly what Sara asked is to use the
-round- function. The variable as they "appear" (presumably after
-list-) are rounded, so why not round yourself when evaluating the
inequality.
*------------ begin example ------------
sysuse auto, clear
gen price2 = price - 0.001
format price2 %8.0gc
list price price2 in 1/10
count if price2 == price
count if round(price) == round(price2)
*----------- end example -------------
(For more on how to use examples I sent to the Statalist, see:

Hope this helps,
