[DBAL-121] Mapping, decimal returns float. Created: 12/Apr/11  Updated: 14/May/11  Resolved: 14/May/11

I have a Doctrine 2 entity and the value is mapped like this (with regular getter/setter):

 * @Column(type="decimal", precision=40, scale=30)
protected $someValue;

 * @return decimal
public function getSomeValue()
    return $this->someValue;

 * @param decimal $someValue
public function setSomeValue($someValue)
    $this->someValue = $someValue;

When I set that value from my code, the value gets written into the database correctly. But, and that is my problem, when I get the value (via getter or \Doctrine\Common\Util\Debug::dump()), it always gives me a number with maximum 14 digits, and it rounds the value. I read the record with the default findById().

eg: with value 1234567890.012345678901234567890123456789 I have 1234567890.0123
eg: with value 890.0123456789012345678901234567890123456 I have 890.01234567890

I of course want all digits, not just 14. The field in MySQL is declared like this:

    someValue decimal(40,30) NOT NULL,

When I get the value with raw PHP and mysql_query(), it returns correctly.

It seems like the problem is that Doctrine returns a float: ["someValue":protected]=> float(234567890.01235)

What's wrong, what should I check next, how to fix, any clues?
