In Excel .5 is always rounded up when the decimal places are reduced,
ie. 3.55 becomes 3.6, 3.65 becomes 3.7 etc. I need a formula that will
"throw .5 to the odd" so that 3.55 would become 3.5, 3.65 would become
3.7 etc.

Someone kindly supplied this yesterday

Assuming your numbers are in column A, try this formula in column B

=IF(A1-FLOOR(A1,1)<=0.55,FLOOR(A1*10,1)/10,ROUND(A1,2))


but unfortunately the formula doesn't "throw to the odd", I know that
"throwing to the even" is called 'bankers rounding' and there is no
function in Excel that supports this. Throwing to the odd is commonly
used in meteorology when working out average temperatures' eg. 12.5 +
3.8 = 16.3 when divided by 2 to give the average it results in 8.15,
when rounded to one decimal place Excel rounds this up to 8.2 when the
figure should be 8.1. It is possible to do this manually but this can
lead to errors.

Any further help appreciated.

Thanks - Kirk

More complex than I anticipated

=IF(AND(ISEVEN(ROUND((A1*10/2),0)),ROUND(MOD(A1,0.1),2)=0.05),ROUNDDOWN(A1,1
),ROUNDUP(A1,1))

a bit simpler

=IF(ROUND(MOD(A1, 0.1),2)=0.05, (INT(A1*10) + MOD(INT(A1*10), 1))/10,
ROUND(A1, 1))

Hi Bob,

If 0.85 should become 0.9 and -3.55 should give -3.5 I would suggest:

=ROUND(A1,1)-(MOD(A1*20,1)=0)*MOD(INT(ABS(A1)*10),2)/10*SIGN(A1)

Regards,
Bernd

Why are you not happy with the user defined function that I provided in your
previous thread on this topic?
