Hi Joe,
The Float field requires a numeric value to be stored, in other words, at any moment it has to have some numeric value associated with it. So a 'blank' field is 0, and the number is formatted to the number of decimal places you specify for that field. It sounds like you have it set to 2 places after the decimal which is the default setting for a float field. If you want the field to be able to default to 'blank', I'd suggest using a text field instead. Of course it won't reformat the number you put in to a fixed set of decimal places, but you can have a blank value and it can be used for calculations as well.
If not, I'd suggest putting something like 0 in the default value, so you have less to delete. Let me know which works best for you!
