Function will probably end up looking something like this.

bool Client::CheckDoubleAttack(bool tripleAttack) {

	//Check for bonuses that give you a double attack chance regardless of skill (ie Bestial Frenzy/Harmonious Attack AA)
	uint16 bonusGiveDA = aabonuses.GiveDoubleAttack + spellbonuses.GiveDoubleAttack + itembonuses.GiveDoubleAttack;

	if(!HasSkill(DOUBLE_ATTACK) && !bonusGiveDA)
		return false;
	
	int chance = 0;
	
	int8 classtype = GetClass();
	
	uint16 skill = GetSkill(DOUBLE_ATTACK);

	sint16 bonusDA = aabonuses.DoubleAttackChance + spellbonuses.DoubleAttackChance + itembonuses.DoubleAttackChance;
	sint16 skillmod = 0; //TODO: Apply all worn skill mods, spell skill mods.

	//Use skill calculations otherwise, if you only have AA applied GiveDoubleAttack chance then use that value as the base.
	if (skill)
		chance = ( (skill*(100+skillmod/100) + GetLevel()) * (100+bonusDA+bonusGiveDA /100)) /500
	else 
		chance = bonusGiveDA + (bonusGiveDA * (100+bonusDA/100));

	//Live now uses a static Triple Attack skill (lv 46 = 2% lv 60 = 20%) - We do not have this skill on EMU ATM.
	//A reasonable forumla would then be TA = 20% * chance
	if(tripleAttack) {
		// Only some Double Attack classes get Triple Attack [This is already checked in client_processes.cpp]
		sint16 triple_bonus = spellbonuses.TripleAttackChance + itembonuses.TripleAttackChance;
		chance *= 20 + triple_bonus /100;
	}
	else 
		return false;
	
	
	if((MakeRandomInt(0, 100) < chance))) 
		return true;
	
	return false;
}
