I can save negative number in properties but get a wrong number when query the property

[cnoork]

I save for instance -6 and when I request the number I get -4294967302
The number will be showed in the payload as:

{"low":-6,"high":-1}

I use the following function to combine the low/high to get that big number which I did not expect:

function highLow(value) {
    if ( value.high && value.low ) {
        var result = value.high * 4294967296 + value.low
    } else {
        result = value
    }
    return result
}

Unfortunately it happens also with positive numbers that the high bit is filled. In the flow I have 4 neo4j function placed.

Thanks for reporting! Do you have any idea on how to fix it?

Unfortunately I am not a software developer and have not that deep knowledge

Neo4j writes int64 as two int32 because javascript has no int64. the two split numbers are send in an object low and high. I interpret these as two separate number and there it went wrong. I convert the value object (with the low and high in it). Solution is much easier but limit the number to int32, in my situation I have never bigger numbers.

value64 = {low: <number>, high: <number>}
value32 = Number(value64)
