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.
