My iPhone is doing math wrong See the images, it's an iPhone 6s, with iOS 10.3.2, does any one have the same issue ? It seems specific to any fraction with three digits after the comma on the denominator within spotlight:



Also, to add some information, it comes back to correct result when I add (or remove) a digit (see image)



And I have a correct result when it is with coma on both numerator and denominator:
I get different results based on whether 1,8/0.083 is used or 1.8/0.083 is used both in spotlight on iOS and macOS.  It would appear that the comma , is ignored and the number is treated as non decimal.

Attached are the results.  One could verify if the region settings make a difference by changing them temporarily to UK or another region.

iOS:





macOS:
