Loop through a decimal sequence

I am writing a loop in VBA for excel, and I would like to loop through a sequence of decimal numbers, rather than integers.

For example:

For i = 1 To 10
    'Do something
Next i

But rather than incrementibg by 1, I would like to increment by 0.5 (or perhaps 5, or really any number other than 1).
