The purpose of this package is to perform automatic compile-time or runtime dimensional checking when dealing with quantities and units.

Requires: DMD 2.065+

Modules

base module quantities.base

This module defines the base types for unit and quantity handling.

math module quantities.math

This module defines common math operations on quantities.

parsing module quantities.parsing

This module defines functions to parse units and quantities. The text input is parsed according to the following grammar. For example:

Prefixes and unit symbols must be joined:: "1 mm" = 1 millimeter; "1 m m" = 1 square meter
Standalone units are preferred over prefixed ones:: "1 cd" = 1 candela, not 1 centiday
Powers of units:: "1 m^2"; "1 m²" (superscript integer)
Multiplication of to units:: "1 N m" (whitespace); "1 N . m"; "1 N ⋅ m" (centered dot); "1 N * m"; "1 N × m" (times sign)
Division of to units:: "1 mol / s"; "1 mol ÷ s"
Grouping of units with parentheses:: "1 kg/(m.s^2)" = 1 kg m⁻¹ s⁻²

si module quantities.si

This module defines the SI units and prefixes.
