if(strcmp(cmd,"/angleo",true)==0)
{
    new Float:angle;
    GetPlayerFacingAngle(playerid, angle);
    angle += 5.0;
    SetPlayerFacingAngle(playerid, angle);
    new string[128];
    format(string,sizeof(string),"Angle: %0.4f",angle);
    SendClientMessage(playerid, -1, string);
    return 1;
}

Try this one. ^^ Should work.
