As it stands now
ceillog2(1) is 0
ceillog2(0) is 32 (should be -infinity or 0 depending on point of view)

I though to use (ceillog2(x) % 32) but it gets issues of its own.

I think the best thing to do is just ignore the issue and remember
that any function with "log" as part of its name does not like 0 as
input.
