Since the update to version 0.7, the conversion rates of goals in the flash chart are integers if the language is set to German. I found out that the reason for this problem is that the character for the separation of decimal places is "," in German, but "." in English.
Changing line 141 in the file /core/Visualization/Chart.php from
$is_decimal_separator_comma = false,
$is_decimal_separator_comma = true,
solved this problem.
Keywords: conversion rates, integers, german
But that change isn't compatible with $is_thousand_separator_disabled = false.
Rolling this issue into #1562.
