Cary R 27cdd27889 Add .cast/int and update .cast/real.
This patch adds .cast/int and updates .cast/real to act as a local
(temporary) net and to support either a signed or unsigned input.
The vvp_vector4_t class not can convert an arbitrarily sized double
to a vector value. This removes the restriction of lround().

Also document the new statements.

Larry Doolittle f60a6561bb Cast strlen to int for printf field width
strlen is a size_t, and the * field width takes an int.
Make this an explicit cast.  It's good for 64-bit machines
and squelches warnings from gcc-4.3.
