fixpoint ==>
fixed point
<mathematics> The fixed point of a function, f is any value, x for which
f x = x. A function may have any number of fixed points from none (e.g. f x =
x+1) to infinitely many (e.g. f x = x). The fixed point combinator, written as
either "fix" or "Y" will return the fixed point of a function.
See also least fixed point.

fixpoint ==>
fixedpoint
<programming> A number representation scheme where a number R is
represented by an integer N such that R=N*B, where B is the (assumed) base of
the representation.
On computers with no floatingpoint unit fixedpoint calculations can be
significantly faster as all the operations are basically integer operations.
Apart from that, fixedpoint representation has the advantage of having uniform
density, i.e., the smallest resolvable difference of the representation is B
throughout the representable range, in sharp contrast to floatingpoint
representations.
