Calculate.js

Calculate.js is kind of an extension to the javascript build-in Math-Library.

Usage

Download the latest minified release and import it within your project.

<script type="text/javascript" src="calculate.min.js"></script>

Abilities

• a powerful term-parser that supports all popular math functions like sin, cos, tan, log, sqrt or pow.
• 33 additional Math-Class extensions
• Geometric classes like Circle, Ball, Cylinder, Rectangle, Triangle, Cuboid
• Term and Function classes to parse and calculate any mathmatical function
• Fraction, Interval and Relations classes to handle those

Coming Soon

• Vectors, Matrizes and Complex Numbers
• More Function-abilities
• Physical Units
• More Geometric classes like Pyramid

Extensions

Calculate.checksum(12345)                       //returns 15
Calculate.isPrime(7)                            //returns true
Calculate.isPrime(6)                            //returns false
Calculate.nextPrime(7, 3, true)                 //returns 13
Calculate.getGreatestCommonFactor(16, 72)       //returns 8
Calculate.logarithm(22, 3)                      //returns 2.813588...

Parser

Parser.calculate("sin(23) + 3")                 //returns 3,39073...
Parser.calculate("sin(23) + 3", "RAD")          //returns 2,15377...
Parser.calculate("2+3*sqrt(12-sin(45)) + 5")    //returns 17,08147...

Function

var fx = new Function("2*sin(x-3)+sqrt(2^3)")               
fx.calculate(4.5)                               //calculates with x=4.5 and returns 2.88078...
fx.getYIntercept()                              //returns y-axes intercept 2.72375...
fx.getTableOfValues(new Interval(-10, 10), 1))  //returns all calculated values from -10 to 10 in steps of 1 (-10, -9, ..., 8, 9, 10)

Fraction

var fraction = new Fraction(14, 18)               
fraction.add(2)                                 //adds 36/18 to the fraction
fraction.cancel()                               //cancels to 25/9
fraction.calculate()                            //returns 1.38888...

Circle

var circle = new Circle(5)               
circle.getArea()                                //returns 78.53981...
circle.setRadius(10)                            //sets the radius to 10
circle.getArcLength(120)                        //returns 20.943951...
circle.toBall()                                 //returns a Ball with radius=10
