       this is my life nowfun hash(i: Long) = (i * 2654435761 % 2.toDouble().pow(32)).toInt()

       @romainguy I needed something to get from mastodon account IDs which are longs to crypto public key IDs which need to be integers for some odd reason. That was the coolest looking hashing function I found

       @friendlymike @romainguy Your function performs the modulo operation on double values. You'll likely want this instead:fun hash(i: Long) = (i * 2654435761 % 2.toDouble().pow(32).toLong()).toInt()This can be simplified to:fun hash(i: Long) = (i * 2654435761).toInt()
