Numbers can be compared with the following functions.
|lessThan x y||Function|
|greaterThan x y||Function|
|lessThanOrEqual x y||Function|
|greaterThanOrEqual x y||Function|
These functions take Lpp Number objects for arguments x and
y and return non-
nil if the comparison is true and
nil otherwise. For each of these functions respectively
nil is returned if x is less than y, x
is greater than y, x is less than or equal to y,
x is greater than or equal to y.
Note that the equality of Numbers can be checked using
and more efficiently using
eql See Equality Predicates.
