I've tried using DECIMAL with (2,2) but it won't let me use this.

I simply want to store a number, for example 7.50 or 10.50. I need to keep both numbers after the decimal though but when I refresh the database it resets the values to 0.99. Any suggestions?

The first digit of the `DECIMAL`

declaration is the *total* digits. You probably want to use `DECIMAL (4, 2)`

. This allows for up to two digits before the decimal and two after.

DECIMAL (yourTotalDigit,yourDigitsAfterDecimalPoint); For Example −. DECIMAL (4,2), it means you can take 4 digits total and 2 digit after decimal point.

M - total length

D - digits right of the decimal point

The declaration syntax for a DECIMAL column is DECIMAL(M,D). The ranges of values for the arguments in MySQL 5.6 are as follows:

M is the maximum number of digits (the precision). It has a range of 1 to 65. (Older versions of MySQL permitted a range of 1 to 254.)

D is the number of digits to the right of the decimal point (the scale). It has a range of 0 to 30 and must be no larger than M.

MySQL assigns the storage for integer and fractional parts separately. MySQL uses binary format to store the DECIMAL values. It packs 9 digits into 4 bytes. For each part, it takes 4 bytes to store each multiple of 9 digits. The storage required for leftover digits is illustrated in the following table:

CREATE TABLE IF NOT EXISTS `table_name` (`id` int(11) NOT NULL AUTO_INCREMENT,`cost` DECIMAL( 10, 2 ) NOT NULL);

This will make the cost column hold a total of 10 digits, 8 before and 2 after the decimal point.

So, if you enter 100.0 in MySQL database, it will show an error like "Out of Range Value for column".

CREATE TABLE `salary` ( `id` int(11) NOT NULL AUTO_INCREMENT, `salary` DECIMAL(10,2) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

`DECIMAL(10,2)`

indicates that `salary`

will hold a total of 10 digits out of which 2 will be after the decimal.

i.e.

8 digits before decimal and 2 digits after decimal.
