Description:
------------
Hi there,

It looks as if a bug that was fixed years ago (https://bugs.php.net/bug.php?id=60083) has reappeared in PHP 7.1.x. While using NumberFormatter::formatCurrency, if you specify CHF (Swiss Francs) as a currency, it will round to the nearest 0.05.

Test script:
---------------
$formatter = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
echo $formatter->formatCurrency(12.99, 'CHF');

Expected result:
----------------
CHF12.99

Actual result:
--------------
CHF13.00

It seems to me this never was a PHP issue, but rather an ICU
issue.  Which INTL_ICU_VERSION do you use?

You are absolutely correct - we were using an out-of-date INTL ICU version (50.x). Upgraded to the latest and the rounding disappears. Really appreciate the help, thanks.
