Dear Martin!
Electronic flies?
See one of my lectures (slides 65-66) concerning rounding. If results have to be recalculated from printouts, results may differ if the original evaluation was based on full precision data - which may lead to avoidable discussions…
Wonderful! This is exactly what I want from my clients. Additionally an MD5-checksum should be used to maintain data integrity. If data-files are attached to an e-mail, the checksum should be sent in a separate e-mail.
❝ […] in general data are used as they appear on the page but with electronic flies the situation is less obvious. some electronic file format is ambiguous concerning correct interpretation and presentation of the file contents. in MS excel, numbers may rounded internally (for example you see 2.35 but the correct number is 2.354324).
