New Comment:
A new test has been merged and old tests updated. They will cause
diffs until Tony merges the code change.

Although I can't reproduce the given testcase on Linux there is a bug
here that stops other testcases working for me, and may cause a port
specific difference in behavior for nobleclem's testcase.
The datatypes of the scale and precision fields in php_oci_out_column
(php_oci8_int.h) should be sb1 and s2 respectively. At the moment they
are both ub2. This, for example, prevents the scale for a FLOAT column
being displayed as -127.
See table 6.8 in Oracle's OCI manual:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14250/oci06des.htm#sthref949
@nobleclem, the scale and precision values returned by the OCI8
extension and Oracle's OCI library are the programmatic definitions of
scale and precision, which are different to the user-level values given
in the all_tab_columns table.
@tony2001, I will commit a new testcase to PHP5 and 6, but will let you
evaluate and merge the datatype fix.

PHP/OCI8 returns exactly what it got from OCIAttrGet(..,
OCI_DTYPE_PARAM, .., .., OCI_ATTR_SCALE, ).
If Oracle Client returns wrong information, we can't change or fix
that.

Description:
------------
When using oci_field_scale to obtain the value stored in
all_tab_columns.data_scale in oracle for a field the value returned is
that in all_tab_columns.data_scale multiplied by 256.
Reproduce code:
---------------
Assumptions:
- field #2 is of type NUMBER(12,2)
- all_tab_columns.data_precision is 12
- all_tab_columns.data_scale value is 2
Code:
$conn = oci_connect('username', 'password');
$stmt = oci_parse($conn, "SELECT * FROM fees");
oci_execute($stmt);
$field_number = 2;
$scale = oci_field_scale( $stmt, $field_number );
Expected result:
----------------
$scale should be assigned the value of 2.
Actual result:
--------------
$scale is assigned the value of 512.
