Localization and expression text
In Architect, expression text is not localized. If a flow author runs Architect in Spanish, for example, and enters decimal values in an expression using a comma as the decimal separator instead of a period, Architect displays an expression error and will not validate the expression.
When entering decimal values in expressions, flow authors should always use the period as the decimal separator or radix.
Architect treats decimal values in a culture invariant manner. Simply, the decimal separator is always a period (.), even if other languages may use a comma (,) as the decimal separator. When your run Architect in another language, it is important to understand that Architect does not switch between commas and periods in expressions.
