Description:
------------
Seems like there has been a change to the var_export-function, when comparing PHP4 and PHP5, as stated below:

PHP4
----
     314                 :         case IS_DOUBLE:
     315               8 :                 php_printf("%.*G", (int) EG(precision), Z_DVAL_PP(struc));
> from: http://gcov.php.net/PHP_4_4/lcov_html/ext/standard/var.c.gcov.php

PHP5
----
     407                 :         case IS_DOUBLE:
     408              42 :                 php_printf("%.*H", (int) EG(precision), Z_DVAL_PP(struc));
> from: http://gcov.php.net/PHP_5_2/lcov_html/ext/standard/var.c.gcov.php

Of some reason, the output don't give the same.
I don't know if it's PHP4 that has always had this problem, or if it's a new problem only existing in PHP5.

However, it gives difficulties, if trying to compare the results or want to output the results float-values to either JavaScript or Database. And especially when trying to create scripts that should work on both PHP-versions (4.x+5.x).

Reproduce code:
---------------
<?php
	$test_value = 1.50;

	setlocale(LC_ALL, 'da_DK.iso-8859-1', 'da_DK', 'danish', 'da');
	echo 'DK: ' . var_export($test_value, TRUE) . "\n";

	setlocale(LC_ALL, 'en');
	echo 'EN: ' . var_export($test_value, TRUE) . "\n";

	echo "\n" . PHP_VERSION;
?>

Expected result:
----------------
DK: 1.5
EN: 1.5

Actual result:
--------------
DK: 1,5
EN: 1.5
