Goals

• Create a class that associates a numeric quantity with a unit of measurement.
• Provide support for simple arithmetic and comparison operations.

Implementation

• An immutable class (Could have been struct but I may try inheritance later)
• Unit is stored in an enumeration
• Supported operations:

• Addition w/ like units
• Subtraction w/ like units
• Multiplication by scalar
• Division by scalar
• Modulus by scalar
• Equals()
• >, >=, <, <=, ==
• IComparable
• ToString()
• Implicit cast to Decimal

The Source

The souce can be downloaded from Github.

Notes

• This class does not support any arithmetic that would modify the unit.
• This class is not suitable for manipulating currencies.

Future Ideas

• Have a CompositeQuantity class that would allow quantities with unlike units to be combined.
• Similar currency class with support for allocations/distributions.
• Provide conversion between units. (Actually I think this would be best placed in an external service. Many situations I deal with require some sort of dynamic conversion ratio.)
