.SH SYNTAX
.B #include <libowfat/rangecheck.h>

int \fBassign\fP(dest,a);
.SH DESCRIPTION
If a and dest have the same type, or the value of a is representable in
the type of dest, do dest=a and return 0.

Otherwise, return 1.

Note: This is a macro, so dest does not have to be a pointer.
.SH BUGS
In the multiplication functions, a return value of 1 signals success and
0 failure. In add_of, sub_of and assign it's the other way around.
