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

Maybe a bit OT, but if you need this only for debuging to understand or retrace some binary operations you are doing, you might take a look on wcalc (a simple console calculator). With the -b options you get binary output.

e.g.

$ wcalc -b "(256 | 3) & 0xff"
 = 0b11
