Handle decimal numbers in mysqli

Question

I have to put the price of some items inside a mysql table. When creating the table I\'m using DECIMAL(10,2) as I don\'t need more than 2 digits after the comma

Answer 1

DECIMAL(10,2) means that 10 is the maximum number of digits to be used. The 2 specifies that there are two on the right side of the decimal. So this means there are 8 digits left on the left side. See the manual

As for the datatype, you should use double as this is for decimal numbers.

Integer has no decimal chars, so it will floor all numbers. String is for text and not numeric values. Blob is for a binary large object, EG: an image
