CakePHP - read() losing decimals from MySQL
===

In MySQL I have:

interest_per_day - 0.00076931506849315


But when I use:

    $variable = $this->InterestRate->find('all', array('InterestRate.interest_type_id' => $interest_type_id));


In my $variable interest_per_day is: 0.000769315


How can I manipulate how many decimals I want from DB?
Should I convert it to VARCHAR in DB? Should PHP lose decimals when calculating with decimal?

It's CakePHP 2.2.

Thank you. :)
