[Scilab-Dev] and(%nan) ==%T

[Samuel Gougeon]

Hello,

I am wondering about the following answers:

--> s = %nan;
--> or(s)
  ans  =
   F

--> and(s)
  ans  =
   T

With this last answer, we have a case such that although all entries are 
false -- otherwiseor() would answer %T--, and()applied to them is True.

Is there a reason for that, or is it a bug?

This behavior was already present in Scilab 4.1.2 and is still here in 
Scilab 6.0-b1

Samuel
