st: trouble with replace and decimals

[Ben Zipperer <benzipperer@gmail.com>]

I am having trouble with the --replace-- command. Below is a simple 
example. My intention is to make var1=9 for all observations with 
var3==1.1. What is wrong with my code?

Thanks for your help,
Ben


. clear

. mata st_addobs(1)

. gen var1 = 0

. gen var2 = 1

. gen var3 = 1.1

. sum

     Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
         var1 |         1           0           .          0          0
         var2 |         1           1           .          1          1
         var3 |         1         1.1           .        1.1        1.1

. replace var1 = 9 if var3==1.1
(0 real changes made)

. replace var1 = 9 if var2==1
(1 real change made)
