How does rounding work?
Edited
PracticeVital rounds the final value displayed for session values on appointments and in Completed Sessions to 1 decimal point, but we do this in a way that you might not be familiar with. We utilize Banker’s Rounding, a standard rounding method that ensures fairness and minimizes bias.
What is Banker’s Rounding and why do you use it?
Banker’s Rounding (also known as round half to even) is different from the traditional "always round up when .5" approach. Instead, it rounds numbers ending in .5 to the nearest even number. This helps prevent consistent rounding bias in large datasets.
For example:
2.25 rounds to 2.2 (since .25 rounds down)
4.875 rounds to 4.9 (since .875 rounds up)
