FreeBSD supplies the Sun math library and I believe it is the default
library. That is, FreeBSD also supplies the CSRG 4.4 Lite math library
code, but it is not the default. The Sun library is built with the following
defines: -D_MULTI_LIBM -D_POSIX_MODE -D_IEEE_LIBM, so you should expect
IEEE behavior. You may also need to include floatingpoint.h at the top
of your code.
Check to see which library you have installed.
