Re: [Paparazzi-devel] Adding type "double" to gen_messages.ml

[Pascal Brisset]

Hi,

I tried to clarify the code in gen_messages.ml . To add a "double" type, 
you will have to
- in sw/lib/ocaml/pprz.ml:
  - add a case in the "value" type (line 37). The float type of OCaml 
actually is a double, so "Double of float" will work
  - add an entry in the "types" list (line 84)
  - handle this new type in all the functions of the file (the compiler 
will help, issuing some warning when the "Double" case is missing)
-  in gen_messages.ml:
  - add a "8" case for the size of the value (197)

Let me know if you think it could be profitable to the community: I 
would do it and commit it to the CVS. By the way, did you check that 
double values are correctly handled by the ARM7 C library ?
