How do I store exact values for numbers in Firestore from the Objective-C SDK?
For instance, if I manually create a field called "abv" with a value of "15.9" it shows that exact value.
However, if I update a value in Firestore from the Objective-C API with an NSNumber value of @(15.9) I get this imprecise value in my Firestore document.
NSDictionary *data = @{@"abv": @(15.9)};
[documentReference updateData:data completion:^(NSError * _Nullable error) {
}];
I understand the issues around floating point imprecision but I don't know how to communicate it in a way to Firebase that resolves it like when you do a manual edit from the web console such as store "15.9" exactly as a number.
