Public predicates

.. index:: between/4 .. _float/0::between/4:

between/4 ^^^^^^^^^^^^^

Enumerates by backtracking a sequence of N equally spaced floats in the interval [Lower,Upper]. Assumes N > 0 and Lower =< Upper; fails otherwise.

| Compilation flags: | static

| Template: | between(Lower,Upper,N,Float) | Mode and number of proofs: | between(+float,+float,+positive_integer,-float) - zero_or_more

---

.. index:: sequence/4 .. _float/0::sequence/4:

sequence/4 ^^^^^^^^^^^^^^

Generates a list with the sequence of N equally spaced floats in the interval [Lower,Upper]. Assumes N > 0 and Lower =< Upper; fails otherwise.

| Compilation flags: | static

| Template: | sequence(Lower,Upper,N,List) | Mode and number of proofs: | sequence(+float,+float,+positive_integer,-list(float)) - zero_or_one

---

.. index:: sequence/5 .. _float/0::sequence/5:

sequence/5 ^^^^^^^^^^^^^^

Generates a list with the sequence of Step spaced floats in the interval [Lower,Upper]. Also returns the length of the list. Assumes Lower =< Upper; fails otherwise.

| Compilation flags: | static

| Template: | sequence(Lower,Upper,Step,List,Length) | Mode and number of proofs: | sequence(+float,+float,+float,-list(float),-positive_integer) - zero_or_one
