A little nicer, but non-standard:
s>number? ( addr u -- d f ) \ gforth
\G converts string addr u into d, flag indicates success
s>unumber? ( addr u -- ud flag ) \ gforth
\G converts string addr u into ud, flag indicates success

However, it's not very useful if you do not know for sure that the
string is text-interpreted as a single-precision integer.

Maybe you would want to write this stuff.

You could make the source files executable, and start them with
#! /usr/bin/env gforth
Or alternatively make a shell script that calls Gforth with your Forth
source file(s).
For distribution you could just make it a tar-ball, with a Makefile
that has an "install" target, and leave it to the users to install it,
and eventually to the distributors to package it up for their
installation.
