Hi folks, i hope you can help me with this small problem.
the user enters two numbers, from which the programm calculates the cross sum and stores it in a variable.
for example 4 | 5 = 9
Problem is the cross sum can only habe one diget.
so if the user enters 8 | 9 =17
then the program should pick the 1 and the 7 and calculate the cross sum again:
8 | 9 =17
1 | 7 = 8
i undersstand that i can check if the result is bigger than 9 but i either then have to select each digit single OR there is some function i didnt find so far.
is there a function to calculate the cross total (checksum)?
thanks for your help!
