TYPO3.Fluid

This micro optimization was now merged to v4 fluid with https://review.typo3.org/#/c/10443/ in ticket #34519

A quick bench with following code proves a simple explicit cast increases performance of that call by a factor of 2-3:

$stringToFormat = '  ';
$runs = 10000;

$start = microtime(true);
for ($i=0;$i<$runs;$i++) {
    @number_format($stringToFormat, 2, ',', '.');
}
echo "Don't cast: " . (microtime(true) - $start) . "\n";

$start = microtime(true);
for ($i=0;$i<$runs;$i++) {
    @number_format((float)$stringToFormat, 2, ',', '.');
}
echo "Explicit cast: " . (microtime(true) - $start) . "\n";

Note: The shutup operator is only used to prevent Warning messages from flooding the output.

Patch set 1 for branch 2.0 of project Packages/TYPO3.Fluid has been pushed to the review server.
