&gt; Writing code is not that tough in Europe - just use a proper i18n library.<p>That only goes so far - the actual code you write has to use decimal commas. You can&#x27;t even export, say a list of numbers, and then directly copy that in to your code.<p>Or for example: Use SQL to print a list of numbers to use for testing queries. If you used i18n, all the numbers would have decimal commas, so you can&#x27;t combine them with a comma to make a list.<p>So you have to turn off i18n, print your list, and make sure it&#x27;s off when you use that list in a subsequent query.<p>Any European programmers here? Do you simply leave i18n off for all low level tools? And just use it for customer facing code?
