Float truncated

[keizersoz]

Hello all, In my WSDL I defined a float

<xsd:complexType name="M01_rowType">
<xsd:sequence>
<xsd:element name="helpdTTSAvg" type="xsd:float"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="M01_tableType">
<xsd:sequence>
<xsd:element name="helpdTTSVal" minOccurs="0" maxOccurs="unbounded" type="tns:M01_rowType"/>
				</xsd:sequence>

I can also see from PHP that I received float values, however SOAP truncates the float to integer, whereas for instance 3.06 is trucated to 3. Does someone has any idea how this can happen?

my php is defined as follows

$strQuery="SELECT \n".
       "ROUND(AVG(CalculateDateDiffHD(C.CALL_DATE, C.DATE_CLOSED)/60),2) AS TTS_TT \n".
                "FROM \n".
               "CALLS C \n".
               "WHERE \n".
              "TO_CHAR(C.CALL_DATE,'YYYY-MM')= TO_CHAR(CURRENT_DATE,'YYYY-MM') \n";
 

        $stmt = OCIParse($db, $strQuery);
        OCIExecute($stmt);
 
        $helpdTTS=new stdClass;
        $helpdTTS->helpdTTSList=array();
        $index=0;
 
        while (ocifetchinto($stmt, $arrResult, OCI_ASSOC)) { // meaning returns associative array,         removed null values, function depprecated
          $helpdTTSVal=new stdClass;
          $helpdTTSVal->helpdTTSAvg=$arrResult["TTS_TT"]*1;
          $helpdTTS->helpdTTSList["helpdTTSVal"][$index]=$helpdTTSVal;
        }
 
        return $helpdTTS;

many thanks in advance,
regards
