Correct datatype for latitude and longitude? (in activerecord)

Question

Should I store latitude and longitude as strings or floats (or something else)?

(I\'m using activerecord / ruby on rails, if that matters).

Update:

Mysql

Answer 1

I would suggest using floats, although it doesn't really make that much of a difference. Floats are easier to do calculations on if you ever desire that in the future.
