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

My solution:

long unsigned int i;
for(i = 0u; i < sizeof(integer) * CHAR_BIT; i++) {
    if(integer & LONG_MIN)
        printf("1");
    else
        printf("0");
    integer <<= 1;
}
printf("\n");
