CoffeeScript Math - exp()

---

Description

The exp() method accepts a number and returns its E^x value. Where x is the argument, and E is Euler's constant the base of the natural logarithms

Syntax

Given below is the syntax of exp() method of JavaScript. We can use the same method in the CoffeeScript code.

Math.exp ( x )

Example

The following example demonstrates the usage of the exp() method in CoffeeScript. Save this code in a file with name math_exp.coffee.

value = Math.exp 1
console.log "The exponential value of 1 is : " + value 
         
value = Math.exp 52
console.log "The exponential value of 52 is : " + value 
         
value = Math.exp 0.78
console.log "The absolute value of 0.78 is : " + value  

Open the command prompt and compile the .coffee file as shown below.

c:\> coffee -c math_exp.coffee

On compiling, it gives you the following JavaScript.

// Generated by CoffeeScript 1.10.0
(function() {
  var value;

  value = Math.exp(1);

  console.log("The exponential value of 1 is : " + value);

  value = Math.exp(52);

  console.log("The exponential value of 52 is : " + value);

  value = Math.exp(0.78);

  console.log("The absolute value of 0.78 is : " + value);

}).call(this);

Now, open the command prompt again, and run the CoffeeScript file as shown below.

c:\> coffee math_exp.coffee

On executing, the CoffeeScript file produces the following output.

The exponential value of 1 is : 2.718281828459045
The exponential value of 52 is : 3.831008000716576e+22
The absolute value of 0.78 is : 2.1814722654982015
