eql?

        # Float.eql?

(from ruby core)
---
    eql?(other) -> true or false

---

Returns `true` if `other` is a Float with the same value as `self`,
`false` otherwise:

    2.0.eql?(2.0)            # => true
    2.0.eql?(1.0)            # => false
    2.0.eql?(1)              # => false
    2.0.eql?(Rational(2, 1)) # => false
    2.0.eql?(Complex(2, 0))  # => false

`Float::NAN.eql?(Float::NAN)` returns an implementation-dependent value.
