 Posted: Mon Dec 10, 2007 4:36 pm Post subject: Rounding time |
 |
|
|
I have come to a small problem where I can find no function that can round time! round() rounds decimal figures but it cannot (it does but wrong) round minutes / hours.
I have this data 0.270230000000000 saved as a numeric format in my PG table. This is some xml describing this row :
| Quote: |
<attr>
<attrlabl Sync="TRUE">FT_COST</attrlabl>
<attalias Sync="TRUE">FT_COST</attalias>
<attrtype Sync="TRUE">String</attrtype>
<attwidth Sync="TRUE">5</attwidth>
<attrdefs>Wake County addressing team (GIS)</attrdefs>
<attrdef>Enhanced Routing - Travel time in minutes
</attrdef>
</attr>
|
How can I make that 0.270230000000 into minutes / seconds ? Any hint is much appreicated!
Thanks

This is how I worked around it .. any other suggestions please bring them forward :
| php: |
$totalsec = $ttime * 60 ; // to make it seconds
if ( intval ($totalsec) >= 60 ) {
//that means more than 1 minutes
$min_remainder = fmod ((intval ($totalsec)), 60);
$min = intval ((intval ($totalsec)) / 60);
}
else { $min = 0; }
$sec = round (($totalsec + $min_remainder),0);
$tajm = $min.":".$sec;

A bug was noticed that the seconds were not computed carefully.
Further investigation showed that I had to fix this function .. and here is how it is now .. should work fine :
| php: |
<?
$time = $_GET['time'];
function make_time ($totalsec) {
// echo $totalsec;
if ($totalsec >= 60) {
$min = intval($totalsec / 60);
$totalsec -= $min * 60;
}
$tajm = sprintf("%02d:%02d", $min, intval($totalsec));
return $tajm;
}
echo $time." is : ".make_time($time) ;
?> |
You can test it here : http://yancho.no-ip.org/~yancho/mt.php?=time=364.588889
Remember to change the value of time so you can test other figures 
Hope it helps u
