A comment on Microsoft's Rust guide for C#/.NET developers.

f16 in Rust is equivalent to float in C#

f32 in Rust is equivalent to double in C#

f64 in Rust is equivalent to decimal in C#

Don't think that's quite right. `float` has 4 bytes, and `double` has 8. The `decimal` type has 16 bytes and does all it's arithmetic in base 10.

Are you quoting some old version? Because the page correctly states that Rust's f32 is C#'s float.

Where are you getting what you wrote?

Rust doesn't (March 2024) have f16. And the other correspondences you wrote are wrong.

There's a crate (several it seems) which realizes an f16 with arithmetic using u16, for example.

That doesn't sound right.

This smells like it was written by an LLM
