Change the value of an object to Long-CodePudding

I want the value of the object to be not a double type but a Long type.

client.db("customDB").collection("chart").insertMany( [{"chart": data.chart}]...


  "chart" : [ 
    {
        "x" : 1635017640000.0, ----->   1635017640000 (LONG NUMBER)
        "y" : [ 
            0.13715, 
            0.13715001, 
            0.13714999, 
            0.13715
        ]
    }
 
]

Thank you :)

parseInt(1635017640000.0) would be the way to go :)

No need to import anything.

Remember to google the issue - in javascript any floating point number is called float and any number without comma is an int or rather "integer"

You can use Math.floor to convert to an integer and strip the fraction.

The Math.floor() function returns the largest integer less than or equal to a given number.

{
  x: Math.floor(123.456)
}
