Doctrine 2 - 2 decimal places on a float?

Question

Annotation:

/**
 * @ORM\Column(type="float", scale="2")
 */
protected $curr_price;

I'm using it with Symfony 2.

And this field becomes a double in MySQL database instead of float with 2 point precision.

What am I doing wrong? I tried deleting the DB, reinserting etc...

Answer 1

/**
 * @ORM\Column(type="float", scale=2)
 */
protected $curr_price;

scale should be an integer, and you are using a string

Answer 2

in the *.yml

curr_price:
    type: decimal
    precision: 10
    scale: 2

Answer 3

Both precision and scale properties work only with the decimal mapping type (link). I suggest you use the decimal type.

As to why it's creating a double field instead of float, I'm not entirely sure. It probably has to do with being compatible with all supported databases. I see no mention of double mapping type so I assume they use the same type for both.
