least fixed point         
<mathematics> A function f may have many fixed points (x such that f x = x). For example, any value is a fixed point of the identity function, ( x . x). If f is recursive, we can represent it as f = fix F where F is some higher-order function and fix F = F (fix F). The standard denotational semantics of f is then given by the least fixed point of F. This is the least upper bound of the infinite sequence (the ascending Kleene chain) obtained by repeatedly applying F to the totally undefined value, bottom. I.e. fix F = LUB bottom, F bottom, F (F bottom), .... The least fixed point is guaranteed to exist for a continuous function over a cpo. (2005-04-12)
Least fixed point         
In order theory, a branch of mathematics, the least fixed point (lfp or LFP, sometimes also smallest fixed point) of a function from a partially ordered set to itself is the fixed point which is less than each other fixed point, according to the order of the poset. A function need not have a least fixed point, but if it does then the least fixed point is unique.

In computing, fixed float describes a method of representing real numbers in a way that number and decimal point value is stored at different location or bytes in a memory allocated to variable unlike floating point. In a typical 4 byte (on little endian platform) fixed float number lower(lsb) 2 bytes are used to store the decimal part of the number just like integer value.
