Hello , i have points system in my server which is following . But i want that admin can give specific points . I mean that admin can only give player points that can be divided by 0.25 . So that admins will be able to give them only 0.25 points , 0.50 points , 0.75 points , 1.00 points , 1.25 points and so on.
Following is my code.

PHP код:

CMD:givepp(playerid, params[])
{
    LoginCheck(playerid);
    if(User[playerid][accountAdmin] >= 3)
    {
        new string[150], id, amount;
    
        if(sscanf(params, "ui", id, amount)) return SendClientMessage(playerid, COLOR_RED, "USAGE: /givepp [playerid] [amount]");
        if(id == INVALID_PLAYER_ID) return SendClientMessage(playerid, -1, "» "red"Player not connected.");
        if(User[id][accountLogged] == false) return SendClientMessage(playerid, -1, "» "red"Player not logged in.");
        format(string, 150, "[PREMIUM POINTS] "red"%s has given %s [%d] Premium Points.", GetName(playerid), GetName(id), amount);
        SendAMessage(-1, string);
        format(string, 150, ""green"[PREMIUM POINTS] "white"You have received "grey"%d "white"premium points from an "red"admin"white".", amount, User[id][accountPP]+amount);
        SendClientMessage(id, -1, string);
        format(string, 150, "» You have given {%06x}%s "white"premium points of "grey"%d"white".", GetPlayerColor(id) >>> 8, GetName(id), amount);
        SendClientMessage(playerid, -1, string);
        format(string, 128, "%s received %d Premium Points from %s.", GetName(id), amount, GetName(playerid));
        Log("premium.txt", string);
        User[id][accountPP] += amount;
    }
    else
    {
        SendClientMessage(playerid, -1, "» "red"You are not authorized to use this command.");
    }
    return 1;
}
