Who have said that? 31499968 value is pretty standard compliant. It
may be not the value you want but it is still valid.

Now for your real problem:

It is possible to have higher precision (quick-hack patch allowing
float values of --vbv-maxrate and --vbv-bufsize attached) but probably
nobody really care about such use case to bother write clean version which
could be committed.
