Re: [libreoffice-users] ROUND function consistency

Sorry, this is NOT a bug. This is exactly the result I expect if I was using VBA in MSO. Read on to 
find out why. 

I say this without looking at the code, but, you specifically told LO to use the VBA version of 
rounding, which is NOT normal rounding. VBA rounding uses bankers rounding. 

https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/round-function

With "Bankers Rounding", when numbers are equidistant from the two nearest integers, they are 
rounded to the nearest even integer; therefore, 0.5 rounds down to 0; 1.5 rounds up to 2.

So, it looks like you are getting the correct answer because you turned on VBA support so the round 
function should act like the VBA round function. If you really were writing a macro using Microsoft 
Office (MSO), you would probably have used Math.Round() (I think that is what it is called) to use 
the rounding that you were expecting.

 I have just put a basic macro together so it will calculate income tax

I needed to round the tax to the nearest cent so taking the easy route I
added Option VBASupport 1 to use the available VB round function.

I then noticed that the VB round function with say round(12.125,2)
rounds down to 12.12 and the LO inbuilt spread sheet function ROUND with
ROUND(12.125,2) rounds up to 12.13.

Is rounding in this situation arbitrary or is there some some convention
for consistency.
