That is the problem with JSON. XML worked much better for integers. And if it is typed with XML schema or XPath, XML has an xs:unsignedLong integer type. I wrote my own command line XPath JSON-query tool and used bigdecimals for JSON numbers. If you do not do much math, bigdecimals are probably even faster than using floats, and much easier to implement. Converting a string to a double float is extraordinary complex. I think it is one of the most difficult tasks in computing. Unfortunately, now the W3C made a new XPath standard that requires JSON parsers to use double for numbers, so I changed my tool to use doubles as well. Now I am struggling with the string<->float conversion. The conversion in the standard library does not work properly. I just looked at another conversion library. 4000 lines of code, and after a 2 hour investigation, it turns out, it also does not work properly.
