Round off decimal values in jquery using toFixed funtion.

Round off decimal values in jquery : 

Before Output : 10

  var total = 10;

  var total = total.toFixed(2);

After useing function :  10.00 

Javascript function to convert color names to hex codes

convert hex codes to color name : 

Step: 1 create manjeet.js file
