AE - fetching decimals / numerics as output parameters bound to PDO::PARAM_BOOL or PDO::PARAM_INT returns floats, not integers

[yitam]

To reproduce,

1. connect with ColumnEncryption enabled (AE on)
2. create a table with one decimal column (or numeric )
3. insert one row of valid data
4. write a stored procedure to fetch the value of this decimal column as output parameter
5. use prepare() to call this stored procedure
6. bind this output parameter to PDO::PARAM_INT or PDO::PARAM_BOOL
7. after execute(), the output param is a float, not integer as expected

For example, a table is created with a decimal(4, 1) column,
if the input is 922.337, the data fetched as output param is 922.3, or
if the input is -922.337, the data fetched as output param is -922.3

If binding the variable as an inout parameter with type PDO::PARAM_INT, and the variable is initialized to an integer, then this problem goes away.

Without AE, given the same inputs above, the output params are 922 and -922 respectively with type PDO::PARAM_INT, or bool(true) / bool(false) as with type PDO::PARAM_BOOL

Fixed in 5.2.1-preview.
