Start Using!

We have numerous classes and functions: Calculator, ... (soon)

Calculator

const json = true; // do you want the response in JSON?
const calculator = new XTFZ.Calculator(json);
const result = calculator.evaluate("fact(2) * /*ignore*/ fact(2) / pow(fact(2), 2)");
console.log(result); // "1"

Features:

Functions:

• evaluate(expression) - evaluate the string
• rad(degrees) - degrees to radians
• deg(radians) - radians to degrees
• pow(x, y) - x to the power y
• root(x, y) - x root y
• log(x, y) - log x base y
• ln(x) - natural log x
• fact(x) - x factorial (x!)

Comments

• You can add comments in the evaluate(expression) function's expression string parameter.
• It must be a single line comment: /* like this */
• This can be used to document your expression
• It works because it uses the javascript eval() method to evaluate. However, non-arithmetic tasks won't work.

Scientific

• We have other functions too, like trigonometric functions - sin() cos() tan().
• Note: Trigonometric functions only work in the expression parameter of evaluate(expression) function.
