Was the page I found that mentioned it, but other pages
didn't mention the banking rounding? So not sure if excell
would use regular rounding in excell, but uses the
banking rounding if using the VBA? Don't have access to
excell so no way to test, and might even vary depending
on what version of excell and/or windows??
Note
This VBA function returns something commonly
referred to as bankers rounding. So be careful
before using this function. For more predictable
results, use Worksheet Round functions in Excel
VBA.
Note sure why neither Calc or Excell give option to select
which type of rounding to use?
Made a test formula to do it.
=IF(AND(RIGHT(TEXT(A1,"##.0000"),2)="50",ISEVEN(INT(A1*100))=1),INT(A1*100)/100,ROUND(A1,2))
That looked at 3 and 4 digits and would round down for 0
to 49 and round up for 51 to 99. 50 would depend on the
original digit to 2nd decimal being even or odd to
determine.
=IF(AND(RIGHT(TEXT(A1,"##.000"),1)="5",ISEVEN(INT(A1*100))=1),INT(A1*100)/100,ROUND(A1,2))
Would work with just looking at 3 digit, and would do same for 0 to 4, and 6 to
9, and then vary if 3rd was 5?
Might be another way, but that seemed to work..
