<=> разве шесть методов сравнения?

<=> в этом операторе, как написано, шесть методов сравнения, я насчитал только пять какой шестой?

<=> (spaceship) it's a Ruby operator a <=> b: If a < b then return -1 If a == b then return 0 If a > b then return 1 If a and b are not comparable return nil

I tried translating this in Google Translate and got the following: ----------------------- <=> Is it six methods of comparison? <=> In this statement, as written, six methods of comparison, I counted only five of which is the sixth? ----------------------- Either Google Translate didn't translate this well, or the question being asked simply doesn't make sense.

Doh... I didn't realize the <=> had an actual meaning. Yeah... it makes sense now. I just thought these characters were used as some sort of bullet. Thanks for clarifying Vagif! Would "==" count if you could repeat "="? In some languages, "<>" is similar to "not" or "!=". Could this apply?

"<>" and "==" are missing from the 5 you already listed.
