Category rational - negativ numerator

[wsalomon]

Hi,

there are a bug in 'rational.hpp' if using negativ 
numerators.
in some cases (num=0,num=-1) the operator< works wrong
and the operator /= allows negativ denominator.

I wrote a little test-programm
file "main_rat_comp_test.cpp" to show this.

a bug fix (only for MS VC++ 6.0) is tried in
file "rational2.hpp"

Greetings

Your fixed code was based on a very old version of boost. 
In future, could you please try to reproduce agains the 
current version?

Your test did pick up an error in the code, for operator/= 
however. A fix has been applied to the library.

Thanks for the bug report!

Already fixed a long time ago; I'm just closing the case.
