SELECT Starts, Rejects,
CASE
WHEN Starts = 0 THEN 1
ELSE (Starts - Rejects) / Starts
END AS Yield
FROM History

Returns Values like this:

Starts - Rej - Yield
0 - 0 - 1 (as expected)
2 - 1 - 0 (should be .5)
12 - 4 - 0 (should be .666)

suspect this is about integer math but having a terrible time with CAST in
an attempt to get proper values.
Any help is MUCH appreciated,

Gonzo
