Don't understand numeric rounding-function

[Lorand]

Hi,

Does anybody know, why the rounding-function on the numeric palette and also the indexing-connector of the "index array"-function round "1,5" up to "2" and "2,5" down to "2".

I learned that a "5" after the comma will always be rounded up.

Ive had a quick look in the context help, it rounds the number to the nearest even integer. Bit odd, as you say .5 is normally rounded up, 

hope it helps

Hi Lorand,

this has been asked before and probably will be asked again...

But Wikipedia has the explanation: bankers' rounding is default for an IEEE754 implementation.
