changing the formatting of a number

[Mickeske]

hey,

working javascript CS4 with number with a lot of numbers behind the decimal isn't easy.

But i can't find anything how can change this...

ex: 12,248481545454 should be 12,25...

help...

[Kasyan Servetsky · Accepted solution]

var number = 12.248481545454;
number.toFixed(2);

[Shonkyin-CF145T]

var number = 12.248481545454;
number.toFixed(2);

Result of above code comes 12.24

But if you want 12.25 then use below code

var number = 12.248481545454;
alert(roundToDP (number ,2))

function roundToDP (val,dig)
{
     // Including all its zeros, lopping off beyond:
     val = Math.round(val*Math.pow(10,dig));
     // Force in decimal point at the right place:
     val = String(val);
   //  return val.slice(0,val.length-dig)+"."+val.slice(dig);
     return val.slice(0,val.length-dig)+"."+val.slice(val.length-dig);
}

WOW!

And I would have done:

var number = Math.round(12.248481545454*100)/100;

Or in function form:

var number = RoundWithDecimal(12.248481545454,2);
function RoundWithDecimal(number,decimals){
    var multiplier = Math.pow(10,decimals);
    return Math.round(number*multiplier)/multiplier;
}
