  "textContent": "scottmcm:\n\n> Now that we have 4 floating point types in the works, we could make `f<N>` work if we wanted\n\nI think we'd need something more complex than that since there are multiple types that can reasonably have size 16 (IEEE 754 half `f16` and brain float `bf16`) and waay more for size 8. there's also x87 `f80` and ppc's 128-bit double double type (not to be confused with IEEE 754 `f128`). This makes me say that's too much complexity to try to have a generic float type like the generic integer types `u<N>` and `i<N>`, so I think having a generic `f<N>` is a bad idea.",
