[TYPO3-core] RFC #16022: Size calculation function can only deal with integers

[Benjamin Mack]

Hey,

this is a SVN patch request.

Branches: trunk, 4.4

Type: bugfix

BT reference: http://bugs.typo3.org/view.php?id=16022

Problem:
The conversion function t3lib_div::getBytesFromSizeMeasurement($limit)
casts the $limit function to integer. Usually you have a value from
php.ini like upload_max_file = 2M, which works fine with that function.

However, if you have values like upload_max_file = 2.5M, the t3lib_div
function fails.

Solution:
Replace the intval() calls with doubleval() calls.

All the best,
Benni.
