Fixed-point arithmetic
WebMar 25, 2015 · Floating points are stored using a mantissa and exponent. They can represent a much wider range of values, but are more complicated to manipulate. For your second question I'm going to assume you're using fixed-point arithmetic. The decimal point is fixed and doesn't move. So for your example: 10001.11 >> 1 = 11000.11 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.

WebOct 7, 2003 · Fixed-point math typically takes the form of a larger integer number, for instance 16 bits, where the most significant eight bits are the integer part and the least significant eight bits are the fractional part. Through the simple use of integer operations, the math can be efficiently performed with very little loss of accuracy. WebMay 13, 2024 · Whether fixed-point arithmetic is suitable for an application depends on what numbers the application needs to work with. Using fixed-point formats does require converting input to the fixed-point format and converting numbers in the fixed-point format to output. But this is also true of integers and floating-point: All input must be converted ...
