[Scilab-users] exists yields double

[Federico Miyara]

Dear all,

I wonder why the function "exists" yields 1 or 0 as doubles, instead of 
boolean. I know there is little distinction between booleans and {0, 1} 
and can be easily converted back and forth. I also know that Scilab is 
not meant to be a strongly typed language. But wouldn't it make more 
sense that this kind of funtion yielded a boolean result?

It challenges reason the fact that "isreal", for instance, yields a 
boolean and "exists" yields a double.

Regards,

Federico Miyara
