-    Historically, pretix recorded tax rates as decimals with two places. Today, pretix supports tax rates with up to

-    "19.00" to "19.0000" without warning. While this is semantically the same thing, we need to assume some pretix API
-    users might run into trouble, either because they treat the value as a string and then map something
-    (e.g. ``if tax_rate == "19.00"``) or process it with a language where this is a significant difference. For example,
-    while in Python ``Decimal("19.00") == Decimal("19.0000")`` is true, in Java
-    ``(new BigDecimal("19.00")).equals(new BigDecimal("19.0000"))`` is false and only
-    ``(new BigDecimal("19.00")).compareTo(new BigDecimal("19.0000")) == 0`` is true.
