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
