The title says it all. Many bigint libraries can produce
div and mod simultaneously, and therefor some Prolog
systems have a divmod/4 predicate.

I stepped over this problem when porting some code:

?- float_pow_half_even(-14744, -3, X).
   error(existence_error(procedure,divmod/4),float_rat_half_even/3).

  • SWI-Prolog
  • Jekejeke Prolog
  • Dogelog Player (planned)

Not needed anymore, was using (//)/2 and rem/2 explicitly.
