An arbitrary constant you expect to multiply by.
Usually, k is not just an arbitrary real number, but an integer, like in cos[(2k+1)π]=−1.
For arbitrary constants to multiply by I think λ (lambda, greek letter) is used.
I agree that k strongly connotes integer, but I wouldn’t expect to see λ used like that if not as a Lagrange multiplier.
