Use it every time you declare a variable, unless you're in too much of a hurry. > > 2. Which numerical datatype to use in which situation when declaring > variables holding numerical data. > Depends a bit what you're trying to achieve. My rule of thumb would be:
- use xs:integer for whole numbers - don't use subtypes of xs:integer - use xs:double for continuous quantities (e.g. length, weight) - use xs:decimal for discrete quantities (e.g. money) - don't use xs:float
