If you accept that PC can calculate integer, it is a Turing machine in some
sense.

Precisely, PC is a physical realization of a Turing machine with physical
limitation.

Turing machine is a mathematical model/abstraction of general computation,
including PC.

a PC can approach to a Turing machine closer and closer , but never be the
same, because the TAPE of a Turing machine is infinite. Given sufficient
storage, in our physical world, they are equivalent in computability.
