Another Increment bug in repeat loops

[DunbarX at aol.com]

Keeping startValues constant but just changing the increment value"

on mouseUp
   repeat with n =   0 to 1 step 0.1 -- 0 is a bad starvalue
          put "," after loopCounter
       end repeat
     put the number of items of loopCounter 
end mouseUp

With an increment of 0.1, and extra loop is run (12)
With an increment of 0.2, the correct number of loops is run (6)
With an increment of 0.5, the correct number of loops is run (3)

The error with "0.1" only occurs with the already posted bad startValues. 
None occur with good startValues.

I didn't try imaginary numbers.
