WebMar 15, 2012 · The basic idea is to use regular integer types to represent fractional values. Fixed-point math is most commonly used for systems that lack an FPU or when you need a few more ounces of performance or precision than the standard floating point types can provide (hint: this is rare). WebThat is, all processes described by the evolution of the fixed-point trajectories are accompanied by the monotonic progress of the Tsallis entropy. In all cases the action of the fixed-point map attractor imposes a severe impediment to access the system’s built-in configurations, leaving only a subset of vanishing measure available.
