st: -replace- does not create an exact copy

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?
Michael
