Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

The rational package provides support for working with rational numbers in Dart, enabling exact arithmetic without floating-point precision errors. It represents fractions as numerator and denominator pairs, offering methods for addition, subtraction, multiplication, division, and simplification. Ideal for mathematical applications requiring precise fractional calculations, such as scientific computing or financial modeling. The package is compatible across all major platforms and integrates seamlessly via Flutter's pub system.
