Well, there are of course still operations that
are cheaper. Such is the case for the code you
posted. Operations such as XOR, AND and OR
should be hard to beat. NEQ is however...
But branching is definitely cheaper than it
used to be. Perhaps “incredibly” is stretching it.
However,

Thank you!

zdivmod Calculates the quotient and the remainder. This is available
because when you calculate the quotient you get the remainder
for free. zdiv and zmod simply call zdivmod with the dummy
variable as one of the output variables.
Why include a wrapper at all? Why not just allow the user t
