Fixed point arithmetic library
The fixedpoint package offers several features that are widely used in DSP applications:
Generate fixed point numbers from string literals, integers, or floating point numbers.
Specify bit widths and signedness, or allow it to be deduced
Various rounding methods
Various overflow handling methods
Configurable alerts for overflow, property mismatches, and implicit casting errors
Arithmetic operations such as addition, subtraction, multiplication, exponentiation
Bitwise operations AND, OR, XOR, and inversion.
Type casting to int, float, bool, str
Built-in string formatting (f-strings or str.format)
Comparisons with other FixedPoint, int, or float objects
The fixedpoint package is unit-tested against MATLAB stimulus (with the fixed point toolbox), making the fixedpoint package a viable, accurate, and cost-free alternative to MATLAB.
The fixedpoint package is released under the BSD license.
