Will there be any data loss when converting between double and decimal in mysql?
Doubles have ~16 decimal digits of precision. So the answer is no, since both types are declared to have 15 decimal digits of precision. (If the types had 16 digits, it would depend on the number stored since the precision of doubles is actually between 15 and 16 digits.)
