Dear Ohlbe

thank you :-)

the Analyst software

❝ This may happen due to rounding. [...] The software will use more digits

❝ than what you get on the printout.


I agree with you, we are using 3 digits for manual calculations and the printout is with four digits

❝ In most software the user can define at least the number of decimals in

❝ the output.


we will try and i will keep you posted

❝ Assessors will probably not recalculate. Some inspectors might. Some

❝ definitely will. But these ones are supposed to know about rounding. And

❝ that's something you can at least try and explain.


would priniting a new set of results with 3 digits be accepted by the accessor, along with the rational behind having two sets of printouts with different results?
Thank you and have a lovely day :-)
