Hi!
i'm new here!
i've been around looking for answers that may help me. I need some math operations but they have to be "kind of" signed.
Let me see if I understood: If i use "+" or "-" actually i won´t have a signed result 'cause i´m not using "signed math".... BUT if i make something like 8-10 .... so.... i´ll have my answer in complement to two??
What i need is a calculation like:
m(k) = 100 e(k) - 81e(k-1) + 100 m(k-1)
(yes... it's part of an iterative algorithm)
I don't need to know if m(k) is positive or negative (in good theory it will be positive each time!) just need every operation goes correct w/its respective sign.... so can I JUST use add and subtract commands of PBP??
