Er...  What's wrong with "%d.%0*d", n / 100, 2, n % 100 in sprintf/printk/etc.
arguments?  It's slightly messier if you want to handle the negatives as well,
but also not impossible - "%s%d.%0*d", n < 0 ? "-" : "", abs(n) / 100, 2, abs(n) % 100
will do it, kernel and userland alike.  And I'm pretty sure it's going to be cheaper
than your solution...
