 # Decimal floating point arithmetic for micropython
-This Python module for [*micropython*](https://micropython.org/) provides support for decimal floating point arithmetic. It tries to overcome the limitations of single precision float numbers (32-bit) and provides a solution when double precision float numbers (64 bit) are not enough.
+This Python module for [*micropython*](https://micropython.org/) and [*CircuitPython*](https://circuitpython.org/) provides support for decimal floating point arithmetic. It tries to overcome the limitations of single precision float numbers (32-bit) and provides a solution when double precision float numbers (64 bit) are not enough.
 
 The Python Standard Library contains the wonderful module [*decimal*](https://docs.python.org/3/library/decimal.html), but it has not been ported to *micropython*. This module provides a small, but valuable, part of the functionality of *decimal*.
