quantities.base

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

Dimensions alias Dimensions = int[string]: The type of a set of dimensions.

Quantity struct Quantity(N, Dimensions dims): A quantity that can be represented as the product of a number and a set of dimensions. The number is stored internally as a member of type N, which is enforced to be a built-in numeric type (isNumeric!N is true). The dimensions are stored as an associative array where keys are symbols and values are integral powers. For instance length and speed quantities can be stored as:

AreConsistent template AreConsistent(Q1, Q2): Check that two quantity types are dimensionally consistent.
isQuantity template isQuantity(T): Tests whether T is a quantity type
prefix template prefix(alias factor): Creates a new prefix function that mutlpy a Quantity by _factor factor.
unit template unit(N, string symbol): Creates a new monodimensional unit.
