Build Status Known Vulnerabilities

Usage

All JSON numbers will be passed to BigNumber in the JavaScript object returned from JSONBigNumber.parse()

example

let input = '{"big":1234567890.123456789,"small":789.012}';

let obj1 = JSON.parse(input);
console.log("JSON", obj1.big.toString());  //'JSON', '1234567890.1234567'
//The number has lost the last 2 digits
let out1 = JSON.stringify(obj1);
console.log("JSON", out1);  //'JSON', '{"big":1234567890.1234567,"small":789.012}'

let obj2 = JSONBigNumber.parse(input);
console.log("JSONBigNumber", obj2.big.toString());  //'JSONBigNumber', '1234567890.123456789'
//No loss of precision
let out2 = JSONBigNumber.stringify(obj2);
console.log("JSONBigNumber", out2);  //'JSONBigNumber', '{"big":1234567890.123456789,"small":789.012}'

JSONBigNumber.js: This file creates a JSONBigNumber property in the global object, setting its value to an object containing a stringify method and a parse method. The parse method uses recursive descent to do the parsing.

Note

For bignumber.js >= v6.0.0 use JSONBigNumber >= v1.0.0 For bignumber.js < v6.0.0 use JSONBigNumber < v1.0.0

JSON is a light-weight, language independent, data interchange format. See http://www.JSON.org/

JSON became a built-in feature of JavaScript when the ECMAScript Programming Language Standard - Fifth Edition was adopted by the ECMA General Assembly in December 2009. Unfortunately the built-in JSON handler makes use of JavaScript Number for handling Numbers in JSON causing the loss of precision for numbers with approximately 15 significant figures.
