Thank you Bernard,

In a very befuddled way I'm trying to work out what they are trying to do
but it's just giving me a headache at the moment.

Maybe you or Mike would be able to work it out if I gave you the next one :-)

=IF(LEN(F13)=8,(IF(I13=1,-75.622,IF(J13 = 1, -24.226,0))),"")


F13 = date ddmmyyyy I13=IF(H13(2004-2)*100+9,1,0)
J13 = =IF(H139+100*(2006-5),IF(G13<7,1,IF(G139,1,0)),0)

G13 = F13 as value
H13 = Lookup returning a value from 0-1

I think what they are trying to do is assign a value to date differences
through the year but there must be an easier way.

Could they have used datedif and then a lookup I wonder?

Do you think the 2 formulae using MOD were so that they could do
calculations with dates as Excel numbers and Years e.g. 2006 (J13)? Would it
not have been easier to use a specific date in 2006 and use the excel date to
do calcs?

Confused .......

Let's look at the first
Suppose F13 hole 12345678
MOD(F13,10^6) says divide F13 by 1 million and return the remainder: you get
345678
MOD(F13,10^4) says divide F13 by 10,000 and return the remainder; you get
5678
The we subtract to get 340000; then divide by 10,000 to get 34

In the second one we find MOD(F13,10^4) again = 5678
Multiply by 100: 567800

Then we add this to the first answer: 567834

Not sure why you would want this but that is what they do

best wishes

Hi everyone,

Is there any chance that some kind soul could tell me what these 2
formulae
are doing please?

F13 is a date

=(MOD(F13,10^6)-MOD(F13,10^4))/10000

=(MOD(F13,10^6)-MOD(F13,10^4))/10000+MOD(F13,10^4)*100

Thank you very much
