I'm working on an RPN calculator (don't ask why...) and I'm having
trouble getting a number from gets - how am I supposed to know whether
it's a number?
At the moment I'm doing [eval(oper) == oper.to_f], which is far from
ideal. Any ideas? You all get to win my calculator if you know of a
better way .
