How to convert float64 to json.Number golang

Question

I have ,

  {"time": 14990, "timeTaken": 5.43420481682}

I want timeTaken as json.Number so I am trying this -

  {"time": 14990, "timeTaken": json.Number(5.43420481682)}

But it is not working.

Answer 1

json.Number is internally, a string. Using strconv.FormatFloat should work.

json.Number(strconv.FormatFloat(123.456, 'e', -1, 64))
