Thank you very much, I thought the operators are alrdy checked by
if (op == "+" || op == "-" || op == "/")
But I did same tests for ushort uint and ulong, but for ulong it
didn't compile.
unittest{
alias sulong = Saturated!ulong;
assert(sulong(18_446_744_073_709_551_610) + sulong(2) ==
sulong(18_446_744_073_709_551_612));
assert(sulong(18_446_744_073_709_551_614) + sulong(2) ==
sulong(18_446_744_073_709_551_615));
It failed to compile
Error: signed integer overflow
So I appended uL to each number and it worked.
assert(sulong(18_446_744_073_709_551_610uL) + sulong(2uL) ==
sulong(18_446_744_073_709_551_612uL));
Was it the right idea to fix it? And if so, do I always have to
use a suffix when the number is bigger than uint?
