Converting floating point to fixed point

Question

In C++, what\'s the generic way to convert any floating point value (float) to fixed point (int, 16:16 or 24:8)?

EDIT: For clarification, fixed-poin

Answer 1

This is fine for converting from floating point to integer, but the O.P. also wanted fixed point.

Now how you'd do that in C++, I don't know (C++ not being something I can think in readily). Perhaps try a scaled-integer approach, i.e. use a 32 or 64 bit integer and programmatically allocate the last, say, 6 digits to what's on the right hand side of the decimal point.
