.net - How do F# units of measure work?

Question

Has anyone had a chance to dig into how F# Units of Measure work? Is it just type-based chicanery, or are there CLR types hiding underneath that could (potentially) be used from other .net languages? Will it work for any numerical unit, or is it limited to floating point values (which is what all the examples use)?

Answer 1

The best (and I think official) place to find out about this is on Andrew Kennedy's blog.

Here are the (current) relevant posts.

• Units of Measure in F#: Part One, Introducing Units
• Units of Measure in F#: Part Two, Unit Conversions
• Units of Measure in F#: Part Three, Generic Units
• Units of Measure in F#: Part Four, Parameterized Types

As I said in the post that your answerer referred to, this is most definitely something that you CAN'T do in C# (though I wish you could).
