it compiles fine
thank you.

But it does not weem to work correctly on my Pentium MMX, 
and my Pentium III (I could also check my AMD K7 server, but I
to have find the g++3.0.rpm pakets first)

using g++ version 3.0.1 from the Debian packages.

Beside the fact that infty/nan limit seem to incorrect,
the division tests fail, uncommenting the exit(1) I get :

Infinity: 0
NaN: 0
Testing + on [-2,2] x [-2,2] step 0.3
Testing - on [-2,2] x [-2,2] step 0.3
Testing * on [-2,2] x [-2,2] step 0.3
Testing / on [-2,2] x [-2,2] step 0.3
-2 / -2 = 1 not in [-2,-1.97] / [-2,0.1300000000000002] = [nan,nan]
-2 / -1.787 = 1.119194180190263 not in [-2,-1.97] / [-2,0.1300000000000002] = [nan,nan]
-2 / -1.574 = 1.270648030495553 not in [-2,-1.97] / [-2,0.1300000000000002] = [nan,nan]
