Even and Odd number

This is my first snipet and it is not fancy at all but it can be useful in some case.

It check if the integer is a Even or a Odd number:

PHP Code:


		
			
stock bool:IsEven(num)
{
    return (num & 1) == 0;
}

stock bool:IsOdd(num)
{
    return (num & 1) == 1;
}

Here an exemple of is use in a simple script that allow only one smoke grenade per two rounds:

PHP Code:


		
			
#include <sourcemod>
#include <cstrike>

new g_iClientSpawnCount[MAXPLAYERS];
new bool:g_bClientBuyedSmokeGrenade[MAXPLAYERS];

public OnPluginStart()
{
    HookEvent("player_spawn", OnPlayerSpawn);
}

public OnClientPutInServer(client)
{
    g_iClientSpawnCount[client] = 0;
    g_bClientBuyedSmokeGrenade[client] = false;
}

public OnPlayerSpawn(Handle:event, const String:name[], bool:dontBroadcast)
{
    new client = GetClientOfUserId(GetEventInt(event,"userid"));
    g_iClientSpawnCount[client]++;
    g_bClientBuyedSmokeGrenade[client] = false;
}

public Action:CS_OnBuyCommand(client, const String:item_name[])
{
    if (StrEqual(item_name, "smokegrenade"))
    {
        if (!IsEven(g_iClientSpawnCount[client]) || g_bClientBuyedSmokeGrenade[client])
        {
            PrintToChat(client, "You are only allow to buy one smoke grenade every two rounds");
            return Plugin_Handled;
        }
        else
        {
            g_bClientBuyedSmokeGrenade[client] = true;
        }
    }
    return Plugin_Continue;
}

stock bool:IsEven(num)
{
    return (num & 1) == 0;
}

Re: Even and Odd number

PHP Code:


		
			
stock bool:IsEven( iNum )

{

    return iNum % 2 == 0;

}

Re: Even and Odd number

Thanks, nice optimization. UPDATED.

Re: Even and Odd number

Code:

stock bool:IsEven(num)

{

    return (num & 1) == 0;

}



stock bool:IsOdd(num)

{

    return (num & 1) == 1;

}

Re: Even and Odd number

Re: Even and Odd number

You can probably just leave off the equality.

Code:

stock bool:IsOdd(num)

{

    return (num & 1);

}

Re: Even and Odd number

Sorry to bump but does it consider 0 as even?
