hi @razaabdi so that's a good question but I would first wonder why you would want more decimal places. As I'm sure you're aware, it's significant figures - not decimal places - that generally guides the precision of the measurement. I would be curious to know why your data would require more that four significant figures.

Yes, good question, sgenzer, actually, I am a PhD candidate and as per the requirement of Journal's reviewer that if I calculate the accuracy up to 3 or 4 digits after decimal so, it would be good to identify the best performance algorithm. But, indeed it is not as important but it is required by one of the reviewer. Thanks,
Raza.

@razaabdi. If you set the fraction digit numbers in the preferences to a higher number then you will increase the number of decimal places of the performance operator.

Look under the Number Format section in the preferences. It is a global setting. Mine is set to five digits. It also affects the performance operators.

Thanks a lot hughesfleming68 for your valuable answer, I have changed it to five digits but it only affects AUC value not accuracy, precision, recall, f-measure, sensitivity, and specificity. Actually, my utmost requirement is four significant figures after decimal in accuracy. Please help me. Thanks,

yes sorry @razaabdi I did not answer before but happy you have a good solution. If your journal reviewer needs a refresher course in significant figures, let me know

Thx @hughesfleming68 - forgot about that setting!
