Line 75:

<source lang="ruby">

Array.new(11) { gets.to_i }.reverse.each do |x|

y = Math.sqrt(x.abs) + 5*x ** 3

begin

puts "#{x} #{(y>400) ? 'TOO LARGE' : y}"

y = Math.sqrt(x.abs) + 5*x ** 3

raise if y > 400

puts "#{x} #{y}"

rescue

puts "#{x} TOO LARGE"

end

end

</source>

Ruby handles numerical overflow by returning Infinity, which is greater than 400.

Ruby handles extremely large values very easily, even on 64-bit systems, so the possibility of an overflow in the above program would be slim.
