--- Comment #5 from José Fonseca <jfonseca at vmware.com> ---
This is failing not only denormals, but also large values.

We could also do IEEE bit manipulation, as glibc does:

 
http://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/ieee754/flt-32/s_floorf.c

It's a lot of logic, but probably the only way to get this right for all
cases...
