How to convert 0.9142857 to just 91

[kadin]

If I divide a number like 128/140= 0.9142857 or 91%. I am trying to get just 91.

I don't think these will work. Am I wrong? Thanks.

round() Rounds the value of the parameter val up or down to the nearest integer and returns the value. If val is equidistant from its two nearest integers (that is, if the number ends in .5), the value is rounded up to the next higher integer.

ceil() Returns the ceiling of the specified number or expression. The ceiling of a number is the closest integer that is greater than or equal to the number.

abs() Computes and returns an absolute value for the number specified by the parameter val.

I may have discovered the answer. Multiply .9142857 * 100= 91.42 and then round.

var num:Number = 128/140 * 100;
trace(num);
trace(Math.floor(num));

Doing:

var num:int = (128 / 140) * 100

would give you the whole integer value 91, whethe rit be 91.4, or 91.7

[poltuda]

var num:Number = 128/140*100;
trace(num);
trace(Math.floor(num));

var num1:Number = 0.9142857*100;
trace(Math.abs(num1).toFixed(2));

You could also just do this:

num = Number(num.toFixed(2)); // trims number to 2 decimal places 

If you want to actually round to 2 decimal places you can try:

function roundNumToLength(number:Number, decimalPlaces:Number):Number {
    var decimal:Number = Math.pow(10, decimalPlaces);
    return Math.round(number * decimal) / decimal;
}

// example:
roundNumToLength(0.941) // returns 0.94
roundNumToLength(0.949) // returns 0.95

srsly, this much discussion over formatting a percentage value in a topic where OP figured out the answer for themselves?

Sure, and lets see how much more discussion we can have without evening discussing the problem!

Haha, I was thinking th same thing
This little question really spawned a long thread...
