Maintain decimal points with 0 in JSON object

Question

My requirement is to maintain the decimal value with 0. Here I have mentioned the sample object below.

let sampleObject = {
    "firstname": "Sundar",
    "lastname": "J",
    "salary": 10000.00,
    "incentive": 6500.50,
    "age": 25
}

I need to display salary and incentive without losing the decimal places even the decimal value as 0. But after parsing this JSON object, decimal point with 0 will be lost. Is there any possibility or work around to do this?
