DV - Dimensional Variables
DV (DimensionalVariable) is a Python library for handling physical quantities with automatic unit checking and conversion. It is a wrapper library to the core Rust library, which contains all the logic. Read more about the project (including extra docs) at https://dv.alextac.com.
Features
- Unit-safe math: Add, subtract, multiply, divide with automatic unit checking
- Easy conversions: Convert between any compatible units
- Comprehensive unit support: SI units, imperial units, and more
- Type safety: Catch unit errors at runtime before they cause problems
Quick Example
from dv_py import DimensionalVariable as dv
# Create dimensioned variables
velocity = dv(10.0, "m/s")
time = dv(2.0, "s")
# Automatic dimensional analysis
distance = velocity * time
print(distance.value_in("m")) # 20.0
print(distance.value_in("km")) # 0.02
# Unit checking prevents errors
mass = dv(5.0, "kg")
distance + mass # Raises DVError: incompatible units!
Installation
pip install dv_py
