Mod
x!y
The mod, modulo, remainder or residue[1] function, denoted by !, is used for modulo in K.
Up until the K4 dialect, the modulo verb had the following characteristics:
xis the dividend andyis the divisor.- left atomic on account of the rotate overload.
From K5 onward, the modulo primitive is flipped and right atomic.[2]
