| bitset::to_ulong |
public member function |
unsigned long to_ulong ( ) const; |
|
Convert to unsigned long integer
Returns an unsigned long with the integer value that has the same bits set as the bitset.
Parameters
none
Return value
Integer value with the same bits set as the bitset.
If the bitset is too long to be represented as an unsigned long, an out_of_range exception is thrown.
Example
// bitset::to_ulong
#include <iostream>
#include <bitset>
using namespace std;
int main ()
{
bitset<4> mybits; // mybits: 0000
mybits.set(); // mybits: 1111
cout << mybits << " as an integer is: " << mybits.to_ulong() << endl;
return 0;
}
|
Output:
1111 as an integer is: 15
