thanks for for the explanation marco, I got that far, I was just not sure about
value=1106
value%=10
its this compound operator im not sure of, what is value equal to now?
I just tried a method comparing the ints a strings using itoa()...
that didn't go well 
... not even worth posting
itoa() seems to overflow when given an unsigned int with an unsigned'esk' value
and when blank spots in the buffer are compared they are random.
