SRFI 143 - Fixnums
This SRFI describes arithmetic procedures applicable to a limited range of exact integers only. These procedures are semantically similar to the corresponding generic-arithmetic procedures, but allow more efficient implementations.
See the SRFI document for more information.

fx-greatest
(fx-greatest)
Returns value of the largest representable fixnum.
fx-least
(fx-least)

fx=?
(fx=? i j)
Semantically equivalent to =.
