In c++. I initialize a bitset to -3 like:
std::bitset<32> mybit(-3);
Is there a grace way that convert mybit
to -3
. Beacause bitset object only have methods like to_ulong
and to_string
.
Use to_ulong
to convert it to unsigned long
, then an ordinary cast to convert it to int
.
int mybit_int;
mybit_int = (int)(mybit.to_ulong());
