strip decimal points from variable

Question

ok i know this is probably really easy but I am floundering.. I have a series of variables that have a decimal point and a few zeros. How do I strip the variable so it goes from 1.000 to 1 ? Dont think this is that important but the numbers are generated from an xml file that I am grabbing with jquery like ...

var quantity = $("QTY",this).text(); 

Thanks in advance for any help!

Answer 1

Simply...

Math.round(quantity); 

...assuming you want to round 1.7 to 2. If not, use Math.floor for 1.7 to 1.

Answer 2

use parseInt();

parseInt("1.25");//returns 1 parseInt("1.85");//returns 1 parseInt(1.25);//returns 1 parseInt(1.85);//returns 1
