back by the code:

() send_money(slice address, int amount) impure inline {
    var msg = begin_cell()
        .store_uint(0x10, 6) ;; nobounce
        .store_slice(address)
        .store_grams(amount)
        .end_cell();

    send_raw_message(msg, 64);
}

• What is the meaning for 64 here for send_raw_message?
• And what is more expand and the usage for .store_uint(0x10, 6)? Is there more than just nobounce? Then what is the number for it.
