mysql field is stored
104.13 in format
With this select, I can see the record:
SELECT * FROM parcelas WHERE valor like '104%';
But with this select it does not appear:
SELECT * FROM parcelas WHERE valor = '104.13';
How do I select values

If you are planning to use a float data type for a column in your database, you should reconsider , especially if you are planning to use it to store monetary values. p>
Attempts to treat floating-point values as comparisons
can cause problems.
