// load math.js (using node.js)

var math = require('../index');

// serialize a math.js data type into a JSON string

var x = math.complex('2+3i');

var str1 = JSON.stringify(x);

console.log(str1);

// outputs {"mathjs":"Complex","re":2,"im":3}

// deserialize a JSON string into a math.js data type

// note that the reviver of math.js is needed for this:

var str2 = '{"mathjs":"Unit","value":5,"unit":"cm"}';

var y = JSON.parse(str2, math.json.reviver);

console.log(math.typeof(y)); // 'Unit'

console.log(y.toString()); // 5 cm
