Unboxed floating-point arithmetic. This file primarily duplicates functionality from the Float module, but for float#.
Unboxed 32-bit integers. This file primarily duplicates functionality from the Int32 module, but for int32#.
Unboxed 64-bit integers. This file primarily duplicates functionality from the Int64 module, but for int64#.
Unboxed processor-native integers. This file primarily duplicates functionality from the Nativeint module, but for nativeint#.
OCaml code that depends on the layout of mixed blocks (via Obj.magic or similar) should include a reference to this value. The value will be removed and replaced with one with an incremented name when the representation of mixed blocks changes, alerting maintainers of code that reference this value to consider whether updates are needed. It is similar in purpose to Assert_mixed_block_layout_v6, a macro used by C code that depends on the mixed block representation for the same reason.
