Dear co-users,
I am somewhat rediscovering that Scilab allows to defined a signed zero:
--> zm = -0
zm =
0.
--> 1/zm
ans =
-Inf
It looks not documented. I am wondering where is the best place to
document it (i mean, which existing page?), and even if it is worthwhile
to document it.
Indeed, what can be done with it? Beside inverting it into -%inf, other
operations are rather disappointing:
--> zm==0
ans =
T
--> zm<0
ans =
F
--> sign(zm)
ans =
0.
Any idea about applications?
Cheers
Samuel
