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.
