As of November 1, 2025, 12:20:24 (), the term “FixedFloat” refers to multiple concepts within the realms of computer science and cryptocurrency. This article will explore these different meanings, focusing on both its technical implementations in Python and its application as a cryptocurrency exchange platform.
Fixed-Point Arithmetic in Python
Fixed-point arithmetic is a method of representing real numbers using a fixed number of integer and fractional bits. This contrasts with floating-point arithmetic, which uses a variable number of bits for the fractional part. Fixed-point representation can be more efficient in certain applications, particularly those with limited computational resources or where deterministic behavior is crucial.
Python Libraries for Fixed-Point Arithmetic
Several Python libraries facilitate fixed-point arithmetic:
- mpmath: A library for arbitrary-precision floating-point arithmetic. While primarily focused on floating-point numbers, it provides the foundation for high-precision calculations that can be relevant to fixed-point implementations.
- fxpmath: Specifically designed for fractional fixed-point (base 2) arithmetic and binary manipulation, offering NumPy compatibility. This library provides tools for performing arithmetic operations directly on fixed-point numbers. (https://github.com/francof2a/fxpmath)
- numfi: Mimics MATLAB’s ‘fi’ fixed-point object, providing a Simulink-like experience for defining word and fraction lengths.
- spfpm: A package for performing fixed-point, arbitrary-precision arithmetic in Python. (https://github.com/rwpenney/spfpm)
- bigfloat: A Python wrapper for MPFR, providing high-precision floating-point arithmetic, which can be used in conjunction with fixed-point calculations.
The choice of library depends on the specific requirements of the application, including performance needs, desired precision, and compatibility with other tools.
FixedFloat as a Cryptocurrency Exchange
FixedFloat is a cryptocurrency exchange platform that specializes in instant, non-custodial cryptocurrency swaps. It distinguishes itself by offering both fixed and floating exchange rates.
Key Features of the FixedFloat Exchange (ff.io)
- Fixed Rates: Users can lock in a specific exchange rate for a limited time, providing price certainty.
- Floating Rates: Offers dynamic rates that adjust to market conditions.
- Non-Custodial: Users retain control of their funds throughout the exchange process; FixedFloat does not hold user funds.
- Security: Emphasizes security measures to protect user transactions.
- Wide Asset Support: Supports swaps across a large number of digital assets (over 1000 as of the information available).
- Transparent Fees: The exchange rate displayed includes all associated fees.
FixedFloat operates as an automated exchange, streamlining the process of swapping cryptocurrencies. It’s designed to provide a fast and secure trading experience.
How Rates are Formed
When a user creates an order on FixedFloat, the displayed amount already incorporates all necessary fees for the exchange. This transparency allows users to understand the total cost of the transaction upfront.
FixedFloat: A Novel Data Type (Google)
Google developed a novel data type called FixedFloat to address limitations inherent in traditional fixed-point numbers. FixedFloat numbers are represented using a 64-bit integer, offering a different approach to representing fractional values.
Python Module for the FixedFloat API
A Python module exists to interact with the FixedFloat API, allowing developers to programmatically create exchange orders and integrate FixedFloat functionality into their applications.
