From manual page:

When setting the locale to fr_CA, using filter_var with decimal numbers is behaving irregularly since the comma is the decimal separator in fr_CA, the sanitized float becomes an int losing its comma.

filter_var is either not coded in a locale dependent way or this below scenario is not being caught in its handling of the locale.

Test script:
setlocale(LC_ALL, 'fr_CA.utf-8');
$number = 25 / 2;

echo $temp;

Expected result:

Actual result:

Not only is FILTER_SANITIZE_NUMBER_FLOAT not locale aware, but
there also is no possibility to manually override the decimal and
thousand separators[1] (like for FILTER_VALIDATE_FLOAT), which
rather limits its usefulness.

In this case one can get around this limitation by using the flag
FILTER_FLAG_ALLOW_FRACTION[2], but that's quite a hack.

This issue is fixed as of PHP 8.0.0[1], where float to string
conversion (which is actually the culprit here) is no longer
locale aware.  This fix won't be backported.
