(from ruby core)

    self < other -> true or false

---

Returns `true` if `self` is numerically less than `other`:

    2.0 < 3              # => true
    2.0 < 3.0            # => true
    2.0 < Rational(3, 1) # => true
    2.0 < 2.0            # => false

`Float::NAN < Float::NAN` returns an implementation-dependent value.
