I have already made the changes.
I made the cast explicit, so that casual readers will understand that the=
=20
types might be different.

I think that most compilers will just ignore a cast from a variable that =
is=20
already in the final type, like in:

=09x =3D (double) y;

The cast should represent no overhead if both x and y are doubles. Do you=
=20
agree?

I never worried about it, except in structure definitions, for padding=20
purposes, and in drivers, where it can matter.
