Prevent JSON.parse(data) from cutting off zero digit for String floats

I am trying to use highcharts to make graphs. I currently have a string which I am looking to convert to a JSON array which looks like the following: 

[{"chart":{"type":"line","renderTo":"chart_0"},"title":{"text":"Daily Sales & Spend"},
"xAxis":{"categories":["08-03-2015","08-04-2015"]},
"yAxis":{"title":{"text":"Dollars"}},
"series":[{"name":"Spend","data":[73.84,73.75]},{"name":"Sales","data":[1020.90,4007.90]}]}]

I need the trailing zeros so that 1020.90 stays 1020.90, on conversion the data becomes the following after the first index:

{"chart":{"type":"line","renderTo":"chart_0"},
"title":{"text":"Daily Sales & Spend"},
"xAxis":{"categories":["08-03-2015","08-04-2015"]},
"yAxis":{"title":{"text":"Dollars"}},
"series":[{"name":"Spend","data"[73.84,73.75]},{"name":"Sales","data":[1020.9,4009.9]}]}

The 1020.90 converts to 1020.9. I think this is a behavior of the float, but is it possible to convert it to 1020.90 [for display purposes]? I need this for displaying the data using highcharts.

This has nothing to do with JSON; this is about how numbers work in JavaScript

The 1020.90 converts to 1020.9

There is no "conversion" here. They're the same number.

Then you need to pad the number with trailing zeros when you convert it to a string.

It is impossible to tell a float how many significant digits it has. You can only impose significant digits when you display the float as a string.
