Example Forms: ACL2 !>(floor 14 3) 4 ACL2 !>(floor -14 3) -5 ACL2 !>(floor 14 -3) -5 ACL2 !>(floor -14 -3) 4 ACL2 !>(floor -15 -3) 5
(Floor i j) returns the result of taking the quotient of i and
j and returning the greatest integer not exceeding that quotient.
For example, the quotient of -14 by 3 is -4 2/3, and the largest
integer not exceeding that rational number is -5.
The guard for (floor i j) requires that i and j are
rational (real, in ACL2(r)) numbers and j is non-zero.
Floor is a Common Lisp function. See any Common Lisp
documentation for more information. However, note that unlike Common Lisp,
the ACL2 floor function returns only a single value,
