FloatOrder
Due to the way floating-point equality works, this instance is not lawful under equality, but is correct when taken as an approximation of an exact value.
If you would prefer an absolutely lawful fractional value, you'll need to investigate rational numbers or more exotic types.

Returns true if x < y, false otherwise.
Returns true if x <= y, false otherwise.
If x > y, return x, else return y.
If x < y, return x, else return y.
Returns true if x != y, false otherwise.
Returns true if x != y, false otherwise.
Note: this default implementation provided by Order is the same as the one defined in Eq, but for purposes of binary compatibility, the override in Order has not yet been removed. See this discussion.

Like compare, but returns a cats.kernel.Comparison instead of an Int.
Has the benefit of being able to pattern match on, but not as performant.
