2 decimal placement

How do i get the DB to display decimal of $152.55 instead of $153.00 The total field in the table is set to Decimal.
I checked the forum but nothing worked.
I checked the locale.php and this is what it has
// currency settings

$locale_info["LOCALE_ICURRDIGITS"]="2";

$locale_info["LOCALE_ICURRENCY"]="0";

$locale_info["LOCALE_INEGCURR"]="0";

$locale_info["LOCALE_SCURRENCY"]="44";

$locale_info["LOCALE_SMONDECIMALSEP"]=".";

$locale_info["LOCALE_SMONGROUPING"]="3;0";

$locale_info["LOCALE_SMONTHOUSANDSEP"]=",";

// numbers formatting settings

$locale_info["LOCALE_IDIGITS"]="2";

$locale_info["LOCALE_INEGNUMBER"]="1";

$locale_info["LOCALE_SDECIMAL"]=".";

$locale_info["LOCALE_SGROUPING"]="3;0";

$locale_info["LOCALE_SNEGATIVESIGN"]="-";

$locale_info["LOCALE_SPOSITIVESIGN"]="";
