does kotlin not have single & and | boolean operator?

[ValV]

AFAIK and and or, but for Int

[karelpeeters]

So a direct answer: no there are no real operators for this.

[tseisel]

Those operators exist for Boolean but are expressed differently :
a & b is a and b
a | b is a or b
Note that there is also a xor operator.

I try to use it for 2 comparisons but it translates to Int's bitwise and/or

[Florian]

ok I have to put the 2 expressions between parenthesis

[Florian]

makes sense

[Florian]

can you clarify for me: boolean and/or/xor boolean has nothing to do with bitwise operators?

[tseisel]

Yes, the link I shared is the documentation of the Boolean type. and, or and xor are all functions that return Boolean. Those are the equivalent for & and |.

[Florian]

thanks

[Icaro Temponi]

These operators are probably coming in the future, there's already a KEEP for them:

[Florian]

thanks

[Florian]

that's only for bitwise operators and not the logical and/or, right?

[tseisel]

Yes, only for numeric types.

[Florian]

are the non-short-circuit logical operators not very popular?

[Florian]

I thought they can be quite useful

[Florian]

but I have no job experience

[karelpeeters]

Very rarely used I'd say.

[Florian]

and this is why they were not added as operators? Or is there another reason behind this?

[karelpeeters]

& and | for booleans are very rarely used, and whether the bitwise operators are used often depends a lot on the domain you're programming in. There's been a lot of discussion about this in #language-proposals, Kotlin discussions and the Youtrack issue.
