Comparison
eq
(eq value &rest values)
eq
returns t if all values
are equal to value
, or nil if any are
not.
For two values to be equal according to eq
, they must have the same
type. In all cases except strings, eq
compares the immediate value
as returned by addr-of
. However, eq
will
return t for strings with identical contents, regardless of their
addresses. To check if two strings reference the same location in
memory, compare their addr-of
.
=
(= value &rest values)
=
compares its arguments numerically. If they are all equal, it
returns value
, otherwise it returns nil. If any argument is not an int
or float, =
returns nil.
<
(< value &rest values)
<
compares its arguments numerically. If the sequence is monotonically
increasing, it returns the last argument, otherwise it returns nil. If
any argument is not an int or float, <
returns nil.
>
(> value &rest values)
>
compares its arguments numerically. If the sequence is monotonically
decreasing, it returns the last argument, otherwise it returns nil. If
any argument is not an int or float, >
returns nil.
<=
(<= value &rest values)
<=
compares its arguments numerically. If the sequence is
monotonically nondecreasing, it returns the last argument, otherwise it
returns nil. If any argument is not an int or float, <=
returns nil.
>=
(>= value &rest values)
>=
compares its arguments numerically. If the sequence is
monotonically nonincreasing, it returns the last argument, otherwise it
returns nil. If any argument is not an int or float, >=
returns nil.
