Putting # after a number forces it to be a real

To force a number to be a real, you can put # after it:

?TYPEOF(4)
1 'integer
?TYPEOF(4#)
0 'real

(The TYPEOF() function can be found here: http://smilebasicsource.com/page?pid=51) You could also use . (or .0 like in most languages), but either way it's pretty much useless.
