What is the name of the <=> operator in Ruby? What do they call it?

Question

In Ruby there is the <=> operator. In the API they do not name its name, just:

The class must define the <=> operator...

Comparable uses <=> to implement the conventional comparison...

...the objects in the collection must also implement a meaningful <=> operator...

What is its name?

Answer 1

See @Tony's above. However, it's also called (in slang) the "spaceship operator".

Answer 2

It's called the Combined Comparison Operator

Combined comparison operator. Returns 0 if first operand equals second, 1 if first operand is greater than the second and -1 if first operand is less than the second.

(a <=> b) returns -1.

Answer 3

This is called the combined comparison operator. Returns 0 if first operand equals second, 1 if first operand is greater than the second and -1 if first operand is less than the second.
