Is there a current way to represent strings as json int?

[Trevinlc1997]

The title may be pretty unspecific but what I am wanting is to give json the string value but without the quotes. (I am not saying for all string values, just ones I ask nlohmann::json to drop the quotes for)
Example: {"Voltage" : "15"} would instead be {"Voltage" : 15}

Now you may be questioning why not just use a int, etc. But the problem arises when I insert a double. I want to only display two numbers after the decimal spot. What my plan was;was insert the number into a string, cut the string after the two decimal spots and then ask nlohmann::json to represent that string as a number.

Here's an example of why I am asking to represent a string as number
What happens: {"Voltage" : 15.430000000001}
What I want: {"Voltage" : 15.43}

This is relevant to #1421. Probably a duplicate?

This could be solved like in #1384.
