Numeric fields with float

Hi,

Many of the dbf files I'm working with store float values as NUMERIC fields, and the Record class treats these as integers:

function getObject($columnObj){
...
case DBFFIELD_TYPE_NUMERIC : return $this->getInt($columnObj);
}

I suggest the creation of a new function getNumeric() that can read both int and float:

case DBFFIELD_TYPE_NUMERIC : return $this->getNumeric($columnObj)

function getNumeric($columnObj) {

if ($columnObj->getType()!=DBFFIELD_TYPE_NUMERIC) trigger_error ($columnObj->getName()." is not a Number column", E_USER_ERROR);
$s = $this->forceGetString($columnObj);
if (!$s) return false;
$s = str_replace(",",".",$s);

//Only differs from getInt() here - Checks if numeric, othewise, converts to integer.

if(is_numeric($s)) return $s;
return intval($s);

}
