Thanks @AndersMS for the care taken to address my concern, and thanks @davidhassell for the proposed revision. A few minor comments:
1. I wonder if users could be given the freedom to do their interpolation at a _higher_ precision than specified by ``interpolation_precision``. I would hate to think that the interpolation method would be degraded by doing so. I suggest, therefore, replacing "the precision should match" with "the precision should match or exceed" or something similar. Also, a comma should follow the introductory clause, "if the interpolation_precision attribute has been set to a numerical value" and typo in "calculatins" should be corrected. 2. I think we should avoid using a specified numerical value in a format that is language dependent. Rather I would prefer following the IEEE 753 standard identifiers of precision. Also, I think "interpolation_precision" might imply something about the accuracy of the interpolation method. To avoid this confusion, perhaps the attribute could be named "computational_precision". I therefore propose the following alternative: - By default, the user may use any precision they like for the interpolation calculations, but if accuracy requires a certain precision, the ``calculational_precision`` attribute should be defined and set to one of the names defined by the IEEE 753 technical standard for floating point arithmetic (e.g., "decimal32", "decimal64", "decimal128"). If the ``calculational_precision`` attribute has been defined, all interpolation calculations should be executed at the specified precision (or higher). In the example, then, "0D" would be replaced by "decimal64". -- You are receiving this because you are subscribed to this thread.
