[C++ HELP] Money

[perdigs]

I need to make in items.xml it recognizes the worth(money) value as follows:

<item id="2148" article="a" name="yen" plural="yenes">
<attribute key="worth" value="0.01" />
<attribute key="weight" value="0" />

to reconigze decimal values example 100 yen equal as 1 zenny.

I believe that changing these codes I can

ItemType::ItemType()
{
	group = ITEM_GROUP_NONE;
	type = ITEM_TYPE_NONE;
	stackable = useable = alwaysOnTop = lookThrough = pickupable = rotable = hasHeight = forceSerialize = false;
	blockSolid = blockProjectile = blockPathFind = allowPickupable = false;
	moveable = true;
	alwaysOnTopOrder = 0;
	rotateTo = 0;

	wieldInfo = 0;
	minReqLevel = 0;
	minReqMagicLevel = 0;

	runeMagLevel = runeLevel = 0;

	speed = id = 0;
	clientId = 100;
	maxItems = 8; //maximum size if this is a container
	weight = 0; //weight of the item, e.g. throwing distance depends on it
	showCount = true;
	weaponType = WEAPON_NONE;
	slotPosition = SLOTP_HAND | SLOTP_AMMO;
	wieldPosition = SLOT_HAND;
	ammoType = AMMO_NONE;
	ammoAction = AMMOACTION_NONE;
	shootType = (ShootEffect_t)0;
	magicEffect = MAGIC_EFFECT_NONE;
	attack = extraAttack = 0;
	defense = extraDefense = 0;
	attackSpeed = 0;
	armor = 0;
	decayTo = -1;
	decayTime = 0;
	stopTime = false;
	corpseType = RACE_NONE;
	fluidSource = FLUID_NONE;
	clientCharges = false;
	allowDistRead = false;

	isVertical = isHorizontal = isHangable = false;
	lightLevel = lightColor = 0;

	maxTextLen = 0;
	canReadText = canWriteText = false;
	writeOnceItemId = 0;

	transformEquipTo = transformDeEquipTo = 0;
	showDuration = showCharges = showAttributes = false;
	charges	= 0;
	hitChance = maxHitChance = breakChance = -1;
	shootRange = 1;

	condition = NULL;
	combatType = COMBAT_NONE;

	replaceable = true;
	worth = 0;

	bedPartnerDir = NORTH;
	transformUseTo[PLAYERSEX_FEMALE] = 0;
	transformUseTo[PLAYERSEX_MALE] = 0;
	transformToFree = 0;
	levelDoor = 0;

	memset(floorChange, 0, sizeof(floorChange));
}

and

else if(tmpStrValue == "worth")
			{
				if(readXMLInteger(itemAttributesNode, "value", intValue))
				{
					if(moneyMap.find(intValue) != moneyMap.end() && (!readXMLString(itemNode, "override", strValue) || !booleanString(strValue)))
						std::cout << "[Warning - Items::loadFromXml] Duplicated money item " << id << " with worth " << intValue << "!" << std::endl;
					else
					{
						moneyMap[intValue] = id;
						it.worth = intValue;
					}
				}
			}

All codes in items.cpp im using TFS 0.3.6
I need a help to change the source to reconigze this decimal values.
