Hi all!
I thought this was solved when I read the word "casting" with reference to the
documentation. This is the problem indeed.
A result is always the same size as the arguments, or the larger argument if
they differ.
(word*word)=word
dword(word*word)= dword(word)
you need to cast one (or both) of your input words to a dword to get the
correct result:
var dword c= (dword(a)*b)/1000

I have this code on a PIC18f27k42 and the output of this is 16 instead of 1000?
5000*200 = 1 000 000, and that fits perfectly in a dword (four bytes).
var word a= 200
var word b= 5000
var dword c= (a*b)/1000
print_dword_dec(lcd,c)
I don't know if it's related to the compiler or to the jallib print_dword_dec()
function. But the answer should be 1000 not 16.
