Is there a printf converter to print in binary format?

Question

I can print with printf as a hex or octal number. Is there a format tag to print as binary, or arbitrary base?

I am running gcc.

printf(\"%d %x %o

One statement generic conversion of any integral type into the binary string representation using standard library:

#include 
MyIntegralType  num = 10;
print("%s\n",
    std::bitset(num).to_string().insert(0, "0b").c_str()
); // prints "0b1010\n"

Or just: std::cout << std::bitset(num);
