Offers a class set for wrapping units of measure and common data structures, supporting Metric and US Customary systems. Extensible design allows easy addition of new units.
A class set for wrapping units of measure and common data structures in a Kotlin application.
A collection of classes representing units of measure and other common data containers that can be used in an application.
Plain numbers are often ambiguous. Consider the method:
fun setLight(brightness: Number)
What number would you pass in to set the light to half brightness?
For measurements, both Metric and US Customary systems are typically implemented. You can also easily add new units by implementing the type's interface. This typically only requires the ability to convert to a common unit, and will allow the new unit to be easily converted between units of the same type.
There are many ways to measure things and store data. This will never be comprehensive, but is designed to be extensible instead. Feel free to add units that you use.
Relying only on base units and composing the unit definitions was considered for the design of this project. However, while technically correct, it made using and maintaining the library cumbersome. It also relied more on math transformations, which increased floating point issues.
This library is designed so that values can be simply annotated by a wrapping value class, maintaining its original number type.
In practice, units that are expressed as ratios, such as kilometers per hour,
should rely on the Ratio type. Units that are given a name should get their
own types, even if they are technically composed from other units.
You would think it'd be Ounces, but it's actually Bels.
No. Math on these units are often done with Double precision. If this is a problem in your application, they can be converted to a plain number for efficiency. In reality, though, it's probably fine.
