- Compare the instance with t and return the result according
to the Prolog defined standard order of terms.

- Convert PlTerm to a
long
and perform standard C-comparison between the two long integers. If PlTerm
cannot be converted a type_error is raised.
- int PlTerm::operator
==(const wchar_t *)
- int PlTerm::operator
==(const char *)
- Yields
TRUE if the PlTerm
is an atom or string representing the same text as the argument, FALSE
if the conversion was successful, but the strings are not equal and an
type_error exception if the conversion failed.
Below are some typical examples. See section
1.6 for direct manipulation of atoms in their internal
representation.
A1 < 0 | Test A1 to
hold a Prolog integer or float that can be transformed lossless to an
integer less than zero. |
A1 < PlTerm(0) | A1
is before the term‘0’in the‘standard order of terms’.
This means that if A1 represents an atom, this test yields TRUE. |
A1 == PlCompound("a(1)") | Test A1
to represent the term
a(1). |
A1 == "now" | Test A1 to be an
atom or string holding the text “now” . |
