16 bits, cast on idct function
Hi all,
Just a stupid question
The IDctSlow function on file idct.c has this line :
ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0);
The ip[0] , _Gd and _Cd are of type ogg_int32_t
My question is:
The result of (_Gd + _Cd) can be a number with more than 16 bits ?
(yes, it can be because they are int32, but the algorithm could
guarantee something about that... I dont know...)
If can, the cast (ogg_int...

int32_t t1, t2;
I've run into this only once or twice over the years but I forget
now how it was resolved then (I think the variable names were changed).
