storing money amounts in mysql

Question

I want to store 3.50 into a mysql table. I have a float that I store it in, but it stores as 3.5, not 3.50. How can I get it to have the trailing zero?

Answer 1

Why do you want to store "3.50" into your database? 3.5 == 3.50 == 3.5000 as far as the database is concerned.

Your presentation and formatting of figures/dates/etc should be done in the application, not the database.
