int, unsigned, float, double etc in financial calculis etc etc

No. Signed types can overflow.

if some of that variables has an overflow it has to rappresent an
error number (eg: INT_MAX for +overflow and INT_MIN for -overflow)
so detect errors in run time is more easy

INT_MAX and INT_MIN are valid values. Using them to represent overflow
is, IMHO, not wise.

for an unsigned thype the aritimetic is very easy

0..UMAX
....
0..UMAX-1 is ok
UMAX is an error

No. Uxxx_MAX is a valid value of that type.
