fix for issue 1011 - set PDO type int for double vars

[axelhahn]

set 'double' => PDO::PARAM_INT to prevent from the value quoting in generator().

I'm having the same issue, if it's a simpe change i wander why the author does not include it. @axelhahn, does your solution works well with decimal numbers?

@jxcodes Huuuh, it was a while ago hat I went ito that trap.

If I have a look to https://www.php.net/manual/en/pdo.constants.php - it says:

 PDO::PARAM_INT (int)
    Represents the SQL INTEGER data type. 

... so: the answer is NO - it doesn't handle float values - it is an integer.

https://www.w3schools.com/sql/sql_datatypes.asp
Database type INT: A medium integer. Signed range is from -2147483648 to 2147483647. Unsigned range is from 0 to 4294967295.

Maybe my issue is, that my integer value was detected as "double" instead of "integer".

If you need to handle a real float value handled as a double - this I didn't tested. Maybe the solution goes into the direction to use the current mappting to PDO::PARAM_STR but to add an if condition in https://github.com/catfan/Medoo/blob/master/src/Medoo.php#L756 that removes the quote chars from a string.

The double data should be PDO::PARAM_STR for database binding, and PDO::PARAM_INT is incorrect.

For generate(), I still think it should handle it as a string with quote(), because it indeed does that for binding.
