What is the difference between int, number and float?
- Well, int are integers, no decimal point (comma in Spain), you know. :-)
- About the difference between number (or decimal or numeric) and float, I really think it's more related with DB internals and how such info is stored, because from their values, they are pretty equivalents (practically, practically, the same).
- Initially I was going to use only one of them (number, I think), but then I discovered we had some of the others (float) currently inside Moodle, so finally I decided to implement both of them. Some RDBMS (Oracle) lacks support for the float type, so we'll convert them to number there).
- Also another possibility is to convert all those float columns (2-3 only) to number to use only that. But, in order to break the minor numbers of things I decided to keep both supported in the XMLDB Schema.
