WebNov 23, 2024 · The term "Fixed-Point" refers to the position of the binary point. The binary point is analogous to the decimal point of a base-ten number, but since this is binary rather than decimal, a different term is used. In binary, bits can be either 0 or 1 and there is no separate symbol to designate where the binary point lies.

WebAn alternate of overflow is saturation, a technique that caps the most positive or most negative value that can be held in a fixed-point representation. This decreases the highly non-linear overflow effect in DSP. The implementation of saturating arithmetic, however, is more complicated than integer arithmetic. http://eecs.umich.edu/courses/eecs373/readings/floating-point-to-fixed.pdf WebFixed Point Arithmetic : Addition and Subtraction; Fixed Point Arithmetic : Multiplication; Fixed Point Arithmetic : Division; Floating Point … high waisted white short
