This is c.l.ada. We're for engineering SW in Ada, not for "C coding".

I have no idea how to convert floating-point values to fixed point in C, and 
this does not seem to be the right place to be asking about that. As far as I 
know, C does not have fixed-point types. Ada does; yet another reason to use 
Ada. If you get a useful answer about C coding here, it will be pure luck. I 
suggest you try c.l.c.

If I'm misinterpreting your question, and this does have something to do with 
Ada, perhaps you can rephrase it in a manner that makes that clear.
