  • The spotlight search box can be used for (simple) math prompts. My Mac (M1 iMac on 15.3.2) has its language set to Dutch. In Dutch, the official way of formatting decimal numbers is the inverse of the us-English way: groups of numbers are separated by a . and decimals with a , . So, for example: 12.345,67 (12 thousand three-hundred forty-five and 67/100).

    When following the official number formatting of the configured language, math in Spotlight works fine. But Dutch people are also human and make small mistakes sometimes, and we also sometimes use a dot to indicate a decimal. But if you do that, spotlight seems to just disregard the decimal and starts showing completely unexpected results:

    5,0 + 5,0 = 10 (expected) 5,0 + 5.0 = 55 5.0 + 5.0 = 110

    Interestingly, while typing the above on my iPhone 12 w iOS 18.3.2, the autocorrect suggestion given after pressing the =-sign was exactly the same…

    Also, this behavior has been around for years, not just the recent MacOS versions. I’m not sure if this also is present when using other languages.

    Thanks for your post and work, and say Hi from me to Tim!
