<=> разве шесть методов сравнения?

Question

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

Answer 1

English?

Answer 2

<|>|=|>=|<=

Answer 3

<=> (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

Answer 4

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.

Answer 5

yes! Is true

Answer 6

why six?

Answer 7

where is "six"

Answer 8

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?

Answer 9

I don't know. This symbols are not in mathematics.
and they symbols have only comparison

Answer 10

show all six Operation

Answer 11

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