This page contains the description of the following commands quomod, quote,

(quomod a b) (Lisp function)

The function (quomod a b) computes then the quotient q and remainder r are computed such that a=bq+r. The remainder is in #:ex:mod, and the quotient is returned. The function (remainder a b) computes the same quantities but returns the remainder. You can divide a polynomial by polynomial by a polynomial. In this case, the degree of r is less than the degree of b. Otherwise, the quotient is an integer, r is non-negative, less than the absolute value of b.

[Endymion] #(quomod  1.2 7)
#quomod : Cannot compute : (1.2 7)
[Endymion] #(quomod  100 7.5)
#quomod : Cannot compute : (100 7.5)
[Endymion] (quomod  #PD_s x^7+1; #PD_s x^2-1;)
#PD_s 1*z + 1*z^3 + 1*z^5;
[Endymion] #:ex:mod
#PD_s 1 + 1*z;

(quote arg) (Lisp special form)

The quote special form takes one argument. The evaluation is the argument. Instead of (quote foo) or (quote (foo bar)), you can say 'foo or '(foo bar): these expressions are read in the same way. Moreover the printer uses this short hand notation.

[Endymion] (list 'quote 1 2 3)
(quote 1 2 3)
[Endymion] (list 'quote 1)
'1
[Endymion] (list 'quote 'foo)
'foo
[Endymion] (eval (list 'quote 'foo))
foo
[Endymion] (eval (list 'quote 'foo 'bar))
quote : wrong number of arguments : 2 this should be 1
[Endymion] (list (quote quote) (quote foo))
'foo
