[fpc-devel] [patch] ucomplex cln() bug

OK, I conclude. My symptoms are: 
z**3-2=                                  NanNani
z*z*z-2=             -2.000000000000000E+000

After digging a bit I realized that this is not a problem of uComplex, but a 
problem of math unit. In particular exp(-Inf) returns NaN, where it should 
return 0. Unfortunately I got really lost when studying the fpc_exp_real 
implementation, and when I saw that the actually used version is in assembly 
I just gave up! 

Any ideas of how it can be fixed? 


Thanks in advance, 
Dimitris
