rounding an integer

[MiCR0]

I want to round off an integer vaule to 10-6 grd from

 

52.71666666  to  52716666

 

0.926888888  to  926888

 

does anyone know a simple way to do this?

Hey!

 

You need to use strlen();  to change length

preg_replace() will remove the fulltop

I think you mean substr() however sure I could do that however if there is a better way as this will loop 100,000 of times

You may want to come up with a more meaningful name for it, but try this function:

 

function removeDecimalAndToSixPlaces($x)
{
    list($number, $decimal) = explode('.', $x);

    $decimal = substr($decimal, 0, 6);

    if (empty($number))
    {
        return (int) $decimal;
    }

    return (int) $number . $decimal;
}

echo removeDecimalAndToSixPlaces(52.71666666); //52716666
echo removeDecimalAndToSixPlaces(0.926888888); //926888

 

There's nothing particular complex within this, so you shouldn't have any performance problems runnning it 100,000 times. Although if this isn't something you plan on re-using, you should take it out of the function wrapper. sbustr couldn't be avoided as numer_format will round up the removed decimal points.
