How does mathjs.config work?

mathjs.config is a function in the mathjs library that allows you to configure various settings and behavior of the library, such as changing the number format, setting the default type of numbers, changing the maximum number of digits, and more. When called, it returns the current configuration object, which can be modified and then re-applied to the library using mathjs.config(configObj).

const math = require("mathjs");

// Define an expression with 5 digits precision
const expr1 = math.evaluate("0.1 + 0.2", { precision: 5 });

// Change the precision to 3 digits
math.config({ precision: 3 });

// Evaluate the expression again with 3 digits precision
const expr2 = math.evaluate("0.1 + 0.2");

console.log(expr1); // 0.3
console.log(expr2); // 0.3

In the example above, math.config() is used to change the precision of math.js. The initial evaluation of the expression "0.1 + 0.2" returns 0.30000000000000004 due to the default precision of 16 digits. After changing the precision to 3 digits, the same expression now evaluates to 0.3.
