Description:
------------
db2 datatype 'REAL' is not supported by ibm_db2 PHP extension. Reading data of that type returns bogus values. Tested against IBM DB2 LUW 9.5.3

Reproduce code:
---------------
<?php
function print_array($res) {
	foreach($res as $key => $val) {
	 echo "$key -- $val \n";
	}
}
$dbcon=db2_connect("test","phorum","p");
$res=db2_exec($dbcon,"CREATE TABLE TEST1R (TZ_OFFSET REAL)");
$res=db2_exec($dbcon,"CREATE TABLE TEST1F (TZ_OFFSET FLOAT)");
$res=db2_exec($dbcon,"INSERT INTO TEST1R VALUES(-2.34)");
$res=db2_exec($dbcon,"INSERT INTO TEST1F VALUES(-2.34)");

echo "Float value\n";
$res=db2_exec($dbcon,"SELECT tz_offset from test1F");
$result=db2_fetch_assoc($res);
print_array($result);
echo "Real value\n";
$res=db2_exec($dbcon,"SELECT tz_offset from test1R");
$result=db2_fetch_assoc($res);
print_array($result);

$res=db2_exec($dbcon,"DROP TABLE TEST1R");
$res=db2_exec($dbcon,"DROP TABLE TEST1F");
?>


Expected result:
----------------
Float value
TZ_OFFSET -2.34
Real value
TZ_OFFSET -2.34

Actual result:
--------------
Float value
TZ_OFFSET -2.34
Real Value
