Rounding to nearest multiple of 0.5 keeping 0.25 as the deciding factor

Jun 22, 2012 12:58 AM

Dear All,

How could I round amounts as illustrated by the following examples in Adobe Livecycle Designer?

8.06 = 8.00, 8.26 = 8.50, 8.74 = 8.50, 8.76 = 9.00

Thanks,

Sandeep

Hi Sandeep,

I don't think there's any trick to doing this, you just have to test and adjust the values yourself, something like;

app.alert(roundToNearestHalf(8.06));
app.alert(roundToNearestHalf(8.26));
app.alert(roundToNearestHalf(8.74));
app.alert(roundToNearestHalf(8.76));

function roundToNearestHalf(number)
{
    var result = Math.floor(number);
    var fraction = number - result;
    if (fraction >= 0.75)
    {
        result++;
    }
    else
    {
        if (fraction > 0.25)
        {
            result += 0.5;
        }
    }
    return result;
}

Regards

Bruce
