>=20

Doesn't seem to? Code please.

Also, the following works for me:

  irb(main):009:0> "   1    45.3456   ".strip.split(/\s+/).map { |i|
                     i.to_i
                   }
  =3D> [1, 45]

(Of course, to_i coerces to integers, so the body of the map block would
have to be more complicated to get floats too.)
