Hmmm
for isnum...
What will that do to the k,m,b? and * and + and things?
Sorry, I just prefer if ($1 == !calc) then adding a space, because if you use it for scripts that have like.... for instance a number association to a person, you can either do !number or !number nick and that doesnt work if there's a space up the top for just !number
correct me if I'm wrong.
