Somebody helpme with sum of floats? - OdgFox - 23.01.2018

I need great help with this problem, the one I want to find but I can not find the way (first time I do a system with floats)

Код:

new MarketInventory[][] =
{
	{float:0.3500, 	10,		" Sprunks"		},
	{float:0.1000, 	15,		" Cigarrillos"	  	},
	{float:0.0100, 	5,		" Billetes de loteria"	}
};

Код:

Dialog:BusinessMarketMenu(playerid, response, listitem, inputtext[])
{
	if(!response)return SendClientMessage(playerid, COLOR_WHITE, "Decidiste no comprar en este negocio.");

	if(PlayerData[playerid][Money] < MarketInventory[listitem][2])return SendClientMessage(playerid, COLOR_WHITE, ERROR_MONEY);
	if(PlayerData[playerid][InventoryWeight] >= MAX_INVENTORY_WEIGHT)return SendClientMessage(playerid, COLOR_WHITE, ERROR_INVENTORY_WEIGHT);

	new i = GetNearestBusinessPoint(playerid);
	switch(listitem)
	{
		case 0: // SPRUNKS
		{
			if(BusinessData[i][Sprunks] == 0)return SendClientMessage(playerid, COLOR_WHITE, "Este negocio no tiene sprunks en su inventario...");

			printf("Pesa: %f", MarketInventory[listitem][0]);
			printf("Inventario del jugador: %f", PlayerData[playerid][InventoryWeight]);

			printf("%f", PlayerData[playerid][InventoryWeight]+MarketInventory[listitem][0]);
			

		}
		case 1: // CIGARRILLOS
		{

		}
	}
	return true;
}

It should print the data correctly ..
(The weight the player has and the weight of the object) but adding amber in a single print gives another value (as seen at the end)

LOG:

Код:

[20:13:32] Pesa: 0.349999
[20:13:32] Inventario del jugador: 1.000000
[20:13:32] 1051931456.000000 // This is supposed to be the sum of both. (1.349999)

pawn Код:

native Float:operator+(Float:oper1, Float:oper2) = floatadd;

This is an operator override for variables tagged with "Float", which is included by default with a_samp (float.inc to be exact). However, you use "float". Those are not the same things. Also, I think if you define a value with a dot, it will be implicitly treated as a variable with Float tag.

I had already read about it, but I did not notice that instead of Float I wrote float, now I get this error if I enter it as Float:

Код:

new MarketInventory[][] =
{
	{Float:0.350,	10,		" Sprunks"		},
	{Float:0.100,	15,		" Cigarrillos"	  	},
	{Float:0.010,	5,		" Billetes de loteria"	}
};

in their respective lines.

I solved the problem, I just had to add the Float: tag.. thanks!

printf("Total: %f", floatadd(PlayerData[playerid][InventoryWeight], Float:MarketInventory[listitem][0]));

You don't need to add "Float:" on a float number. Also, on your array ; you have 3 differents types. You should declare an enumation with those 3 types to make the compiler understand what are you doing. In this enumeration, you must have a variable with a "Float:" tag.

You should've declared "Float:" on a situation like this where the number is not predefined.

new Float:X, Float:Y, Float:Z;
