Concrete float type to coerce values into, e.g.
Concrete error type for errors encountered when coercing values.

This coercion mechanism is used by Ruby to handle mixed-type numeric operations: it is intended to find a compatible common type between the two operands of the operator.
If a Ruby
nil is given, an error is returned.
If the given value does not subclass
Numeric, an error is returned.
