=begin
Random#float happily accepts Infinity and NaN as arguments. It should reject them for three reasons:

• Accepting an argument of Infinity implies that the value returned will be between 0.0 and Infinity, when in fact Infinity is always returned.
• If Infinity or NaN were given by mistake the method would function without error despite not even being pseudo random. That is very dangerous.
• NaN is meaningless as maximum value.
