JSON Number
A numeric value that can be an integer or a floating-point number. It is not enclosed in quotes.
Numbers in JSON follow the standard double-precision floating-point format. They are written without quotes. JSON does not distinguish between integers and floating-point numbers, nor does it support formats like octal, hexadecimal, or non-numeric values like NaN or Infinity.
