  • Portability notes: This object will use the backend Prolog system between/3, plus/3, and succ/2 built-in predicates when available.

Public predicates

between/3

Returns integers in the interval defined by the two first arguments.

Compilation flags:
static
Template:
between(Lower,Upper,Integer)
Mode and number of proofs:
between(+integer,+integer,+integer) - zero_or_one
between(+integer,+integer,-integer) - zero_or_more

plus/3

Reversible integer sum. At least two of the arguments must be instantiated to integers.

Compilation flags:
static
Template:
plus(I,J,Sum)
Mode and number of proofs:
plus(+integer,+integer,?integer) - zero_or_one
plus(+integer,?integer,+integer) - zero_or_one
plus(?integer,+integer,+integer) - zero_or_one

succ/2

Successor of a natural number. At least one of the arguments must be instantiated to a natural number.

Compilation flags:
static
Template:
succ(I,J)
Mode and number of proofs:
succ(+integer,?integer) - zero_or_one
succ(?integer,+integer) - zero_or_one

sequence/3

Generates a list with the sequence of all integers in the interval [Inf,Sup], assuming Inf =< Sup.

Compilation flags:
static
Template:
sequence(Inf,Sup,List)
Mode and number of proofs:
sequence(+integer,+integer,-list(integer)) - zero_or_one
