vincent3569 on "improvement of googleMap plugin"

Hi,

I am trying to to some improvement of googleMap plugin.

In order to do that, I have some questions:

1/ you replace ',' by '.' in exifs data 3 times in the plugin :
- in googleMap.php, function getGeoCoord()
- in GoogleMap/googleMap.php (as a hack of original class),
     - function getAddMarkersJS()
     - function getMapJS()

with 3 times ? the first one in googleMap.php seems to be enough , don't you think ?

2/in googleMap.php, function getGeoCoord()
why did you write that code ?

$lat_c = explode('.',str_replace(',', '.', $exif['EXIFGPSLatitude']));<br />
$lat_f = round((float) abs($lat_c[0])+$lat_c[1]/pow(10,strlen($lat_c[1])),5);<br />

why this code in not enough to convert string in float:
$lat_f = round((float) (str_replace(',', '.', $exif['EXIFGPSLatitude'])),5);

3/ in googleMap.php, function getGeoCoord()
if (strtoupper(@$exif['EXIFGPSLatitudeRef']{0}) == 'S')
can you explain that code ? I amunable to understand what it means...
