Unitforge

Overview

Unitforge is a Rust crate designed for safe handling of physical quantities of units. New quantities and relations can be set up via small macros.

Features

  • Quantity inference: Resulting quantities of arithmetic operations are inferred at compile time.
  • Unit conversion: Quantities can be set or read in arbitrary units.
  • Computing Precision Values are stored in exponential format (f64*10^i32) to prevent floating point precision issues.
  • Formating Quantities are displayed with 4 significant digits and configured display unit.
  • ndarray support: Quantities may be used as inner types for ndarray.
  • 3D Vector and matrix operations: Structs for 3D vectors and matrices are included to allow fast and unit-safe work with them.
  • Serialization: Optional support for sere using the serde feature.
  • python interface Optional Python interface when building with flag pyo3; also available on pypi
