st: recast float to integer produces change, but round(var)-var=0

[maximer@andrew.cmu.edu]

Dear listserv member,

I hope someone can help me with this possibly basic question.

I have a "var" stored as a float.

let

"gen diff = round(var) - var".

I also have:

"count if diff!=0" returns: 0.

However,

"recast int var, force" leads to "X values changed" (where X>0).

I am puzzled, I would have expected "0 values changed". Can someone
provide an explanation.

Many thanks

Maxime Roy
