########## File path: arrow/src/array/array_binary.rs ########## @@ -728,8 +730,11 @@ impl From<ArrayData> for DecimalArray { impl fmt::Debug for DecimalArray { fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { write!(f, "DecimalArray<{}, {}>\n[\n", self.precision, self.scale)?; + let point_index = 10_i128.pow(self.scale as u32); Review comment: I didn't find display.rs, thanks! Your question is really good. While Decimal has custom logic, this doesn't seem to be Decimal specific, e.g. There is a great overlap between display.rs, csv_writer and even the specific array debug formats. I think it should be refactored in a separate issue. -- This is an automated message from the Apache Git Service.
