Float not correct in MySQL

Question

I am entering \'35444650.00\' as a float into my MySQL and it keeps reformatting to 35444648.00, any help welcome...

Answer 1

The MySQL manual claims that FLOAT, REAL, and DOUBLE PRECISION fields stores values as approximate and INTEGER, SMALLINT, DECIMAL, and NUMERIC fields stores values as exact.

I think best bet to overcome this precision issue is to use decimal.
