      Description

      Following realm/realm-swift#7868 I have another issue while saving Decimal128 values. Sometimes, the app crashes when inserting a Decimal128 value that has large significant digits. I noticed that it happens for quotient values less than 100.

      For example, app crashes using the same values from the referenced issue:

      @Persisted var grossPrice: Decimal128 = 70
@Persisted var vatValue: Double = 1.09

grossPrice / Decimal128(floatLiteral: vatValue) = +6422018348623853211009174311926606E-32

      I randomly tested quotient values greater than 100 and it seems to work.
