#40653 [NEW]: strval() and floatval() behave differently

From: plyrvt at mail dot ru
Operating system: Any
PHP version: 5.2.1
PHP Bug Type: Strings related
Bug description: strval() and floatval() behave differently

Description:
------------
Either strval() or floatval() is buggy. They can respect locale or ignore
locale, but at least both do things the same way!

Reproduce code:
---------------
<?php
setlocale(LC_NUMERIC, "ANY_LOCALE_WITH_,_SEPARATOR");
$f=1.2;
$s=strval($f);
$f=floatval($s);
var_dump($f);

// expected: 1.2 or 1,2
// actual: 1
?>

New Comment:

The point is that string representation of doubles (i.e.
double-to-string) always depends on locale settings.
But string-to-double always ignores locale and uses "." as decimal
separator.
That might sound inconsistent, but consider this first:
1) we DO want users to be able to output numbers in locale-dependent
format;
2) we DON'T want scripts to depend on locale or we may end up with
scripts working/not working with particular locales.
