I need to show the value 29.89 like this. but not need to show like that 29.0, If after whole number is start with 0 means we need not show.
Example:
27.0 ==> 27 only
27.9 ==> 27.9 this is wright.
how to remove the 0 from first one using javascript
This is the default behavior of JavaScript:
alert(29.100) => "29.1"
alert(28.000) => "28"
document.body.innerHTML = 29.100 => 29.1
document.body.innerHTML = 28.000 => 28
etc.
Use following parseFloat("YOUR-NUMBER")
Here's an example how it works http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_parsefloat
Try this
Math.round(num * 100) / 100
It seems, that the value is stored in string. Cast the value to float, and it should remove the point by itself.
You can add a function to Number object and use it anywhere in your page /project.
Add function to Number object
Number.prototype.myPrecision = function(){
if(Math.round(this)==this){
return parseInt(this);
}
else{
return this.toFixed(2);
}
}
How to use
var n1 = 10.11;
var new_n1 = n1.myPrecision(); // This will output 10.11
//Other case
var n2 = 10.00;
var new_n2 = n2.myPrecision(); // This will output 10
