unum's Issues

unum_log not implemented?

Hi,

I note that unum_log does not appear to be in the library, although it appears in the unum.h file. Is this correct?
Cheers Hugh

Errors in some calculations

Hi,
I am noticing some peculiarities in some of the calculations. For example:
I expect this:

r-237-121-25-172:lab5 hugh$ ./unumcalc 1 div "[0,2]"
   Result of 1 div [0,2] is NaN
r-237-121-25-172:lab5 hugh$ ./unumcalc 1 div "(0,2]"
   Result of 1 div (0,2] is [0.5,Inf)

But I am surprised by this:

r-237-121-25-172:lab5 hugh$ ./unumcalc 1 div "[0,1]"
   Result of 1 div [0,1] is NaN
r-237-121-25-172:lab5 hugh$ ./unumcalc 1 div "(0,1]"
   Result of 1 div (0,1] is NaN

It appears that if the dividend is the same value as the upper bound of the divisor, then the result is wrong:

r-237-121-25-172:lab5 hugh$ ./unumcalc 2 div "(0,2]"
   Result of 2 div (0,2] is NaN
r-237-121-25-172:lab5 hugh$ ./unumcalc 3 div "(0,3]"
   Result of 3 div (0,3] is NaN
r-237-121-25-172:lab5 hugh$ ./unumcalc 4 div "(0,4]"
   Result of 4 div (0,4] is NaN

Anyway - has anyone else noticed this behaviour?
Cheers Hugh
