i need to round numbers in a spreadsheet 2 decimal points, in a way that:
for a number with a.byX for x>5 i need to round upwards for x<5 i need to round downwards for x=5 i need to round up if y is odd and round down if y is even for example 0.563~0.56 0.566~0.57 0.575~0.58 0.565~0.56 i tried using if, roundup, rounddown, floor,, cant seem to get it right any ideas

Just set the cell format to show the number of digits you want. Setting the precision in the cell format does exactly what you need.

There is always the ROUND function. You can also do a user defined function.

but the round fuction always rounds 5 upwards,
0.5>1 1.5>2 2.5>3 3.5>4..... i need 0.5>0 1.5>2 2.5>2 3.5>4 4.5>4 always rounding to the even number, only that i need it to the 2nd decimal point no to the whole number

As long as you're only dealing with rounding numbers with 3 decimal places down to 2 decimal places, this will work:
=IF((RIGHT(A1,1)<>"5"),ROUND(A1,2),IF(ISODD(A1*100),ROUND(A1,2),TRUNC(A 1,2))) Enter this formula in any cell except A1. Enter your number in cell A1. To make this work for other types of numbers, I would write a user defined function in VBA.

The example's not flawed, the explanation is a bit unclear though.
"b" refers to the 1st digit to the right of the decimal point "y" refers to the 2nd "x" refers to the 3rd His rules state that for "x" > 5, round upward, therefore in 0.566, "x" is equal to 6 which is greater than 5, so round upward to 0.57

I see. sorry. In hindsight I see that it was perfectly explained all along.
