C++ <bitset> - to_ullong() Function
The C++ bitset::to_ullong function returns an unsigned long long with the integer value which has the same bit representation as the given bitset.
Syntax
unsigned long long to_ullong() const;
Parameters
No parameter is required.
Return Value
An integer value which has the same bit representation as the given bitset.
Exception
Throws overflow_error, if the bitset size is too big to be represented by the return type.
Example:
The example below shows the usage of bitset::to_ullong function.
#include <iostream>
#include <bitset>
using namespace std;
int main (){
bitset<10> bset("1110000111");
//converting bset into unsigned long long integer
unsigned long long i = bset.to_ullong();
cout<<bset<<" as unsigned long long integer is "<<i<<".\n";
return 0;
}
The output of the above code will be:
1110000111 as unsigned long long integer is 903.
