Bug description:mysqli: truncated floats
Description:
------------
There's an inconsistency in behaviour between mysqli and PDO_MSYQL in the
following SELECT, e.g.,
SELECT TRUNCATE(SUM(aFloatColumn),2) FROM aTable;
Let's say the sum of the column is 42.001.
With PDO_MYSQL, you'll get "42.00".
But with MYSQLI, you'll instead get "42".
Test script:
---------------
<?php
$link = mysqli_connect("localhost", "user", "password", "dbname");
$query = 'CREATE TABLE t (f FLOAT)';
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
$query = 'TRUNCATE TABLE t';
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
$query = 'INSERT INTO t (f) VALUES (42.001)';
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
$query = "SELECT truncate(sum(f), 2) from t";
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $revenue);
while (mysqli_stmt_fetch($stmt)) {
printf ("%s\n", $revenue);
}
mysqli_stmt_close($stmt);
mysqli_close($link);
Expected result:
----------------
42.00
Actual result:
--------------
42
