The floats in the structs are unboxed. Float arrays and all-float structs have a special representation[1] in the compiler so they are stored unboxed. I believe the developers of OCaml have expressed some regrets about this, but in this particular case it's likely to be a win. Within functions, the OCaml compiler can assign floats to registers, so those would also be unboxed at least for the duration of the function.
