[Scilab-users] algebra conventions with integer types to be discussed

[Stéphane Mottelet]

Hello all,

Integer types in Scilab are not smoothly implemented and there are still 
some bugs and real questions to be discussed, specifically on 
over/underflow, exceptions in divisions such as in

int8(1)/int8(0)

int8(-128)/int8(-1)

type of the result of mixed double/integer operations, such as

int8(1) + %pi

int8(1)/0.0

and so on. Other software related to Scilab, e.g. Matlab and Julia, have 
different conventions and currently Scilab currently adopts a mix of 
them, which does not help to make one's mind.

Integers types were a long-waited feature by people who needed it, so I 
would like to have some  developpers and user testimonies about the way 
they do algebra with them.

Thanks in adavance,

S.
