Try this one,

pawn Код:

CMD:givemoney(playerid, params[])
{
    new
        pid,
        money
    ;
    
    if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFF0000FF, "You Are Not Admin But You Allowed To Use /pay");
    if(sscanf(params, "ui", pid, money)) return SendClientMessage(playerid, 0xFFFF00FF, "Usage : /{FF0000}GiveMoney {FFFF00}[ID] [Value]!");
    if(!IsPlayerConnected(pid)) return SendClientMessage(playerid, 0xFFFF00FF, "Player Doesn't Exist!");

    new pName[MAX_PLAYER_NAME], Str[128];
    GetPlayerName(playerid, pName, sizeof(pName));
    format(Str, sizeof(Str), "Admin : %s Gave You $%i Cash!", pName, money);
    SendClientMessage(pid, 0x00FF00FF, Str);
    GivePlayerMoney(pid, money);
    return 1;
}

PS: You have created a local variable to hold the amount as an integer var and you're using it as float, that won't gonna work at all.
