s>number? should just leave a flag indicating success on the top of stack,
followed by the number the string was converted to. However, when I run it,
there is a 0 between those two values on the stack. It is always a zero,
regardless of what string I give it so far. To test, just do something like
clearstacks s" 1001" s>number? .s
Which will give
<3> 1001 0 -1
Either the code or the documentation must be wrong.
I'm on gforth 0.7.9_20160923 amd64.
