Tips on maintaining the numerical value while using JSON.stringify()

Having trouble using the JSON.stringify() method to convert some values into JSON format. The variable amount is a string and I want the final value in JSON format to be a number, but it's not working as expected. Even after applying JSON.stringify(), the output remains as "price":"1.00". Any suggestions on how to ensure the final value in JSON is a number? Appreciate your assistance!

This is my current code snippet:

var data = JSON.stringify({
 "payer": "a cat",     
 "price": parseFloat(amount).toFixed(2),
});

Answer №1

toFixed will give you a string value as output. If you prefer to have a number instead, simply use parseFloat:

JSON.stringify({
  "payer": "a cat",
  "price": parseFloat(amount)
});

It seems like the only way to display a number with specific decimal precision is by converting it into a string.

I believe utilizing Number() should also yield the desired result.

var data = JSON.stringify({
  "payer": "a cat",
  "price": Number(amount)
});

Dealing with generating random float numbers can be tricky, but I found a solution that works for me:

// Generate a random floating point number between 10 and 120 with exactly 2 decimal places
var randomNumber = Math.floor((Math.random()*110+10)*100)/100

This method ensures that the number remains a floating point value with 2 decimal places even after using JSON.stringify()

This method has proven effective for me.

function modify(key, data) {
  if (typeof data != "object") {
    let updated = parseFloat(data);
    return updated;
  }
  return data;
}

const request = JSON.stringify(parameters, modify);`

Parameters is a variable storing a query parameter.
