#997. Sum of digits

when green flag clicked
set [n v] to (18446)
set [s v] to (0)
repeat until <(n) = (0)>
change [s v] by ((n) mod (10))
set [n v] to ([floor v] of ((n) / (10)))
end
say (s)

    n = math.floor(n / 10)
print(s)

// Scratch's mod gives a positive remainder even for negative numbers
