Equal

True equality

(equal x y) is equal to t or nil, according to whether or not x and y are the same value.

For a discussion of the various idioms for testing against 0, See zero-test-idioms.

Subtopics

Eql
Test equality (of two numbers, symbols, or characters)
Eq
Equality of symbols
=
Test equality of two numbers
Eqlablep
The guard for the function eql
Hons-equal
(hons-equal x y) is a recursive equality check that optimizes when parts of its arguments are normed.
Eqlable-listp
Recognizer for a true list of objects each suitable for eql
