I mistakenly posted this question as a sub-question in an unrelated  
thread; my apologies.
Here's this issue:
For some reason, the following command:
	. bysort var1 : replace var1 = cond(_n == 1, x, y)
replaces the variable var1 with a number not *exactly* identical, such  
as:
	58.29999924 instead of 58.3.
Although I could say:
	. format %9.2f,
that won't find a match for -if-, as in:
	. ...  if var1==58.3
How should I correct that command?
