don't assert on bad args, instead return an error..

Since so many programs don't check return value, always NUL terminate
the buf...

fix rounding when using base 1024 (the bug that started it all)...

add a set of test cases so we can make sure that things don't break
in the future...

Thanks to Clifton Royston for testing and the test program...
