Explain the Formula

Well, the explanation would have a logical and a technical part. Without context, we can only guess the logical part.

So that leaves the technical part.

Shortly summarized it is a conditional calculation of some values. The result is rouded to 2 decimals.
It looks like the formula is designed to be copied down.

Cells $W$8 and $W$5 are TRUE/FALSE values.
If $W$8 is TRUE then the calculation is: SUM(H$12:H12)+G13-$W$9. If the outcome is negative, then 0 is returned. Also if $W$8 is FALSE.
Remark: on the first line with this formula, SUM(H$12:H12)+G13+$W$9 is the value in H12+G13-$W$9.
Copied down 1 cell gives the sum of H12 and H13 + G14 - $W$9.
Copied down another cell gives the sum of H12,H13 and H14 + G15 - $W$9. Etcetera.

If $W$5 is TRUE, then $W$6 is subtracted from G13, with a maximum of 0.
Copied down 1 cell gives G14-$W$6, with a maximum of 0.

From the results of both conditions ($W$8 / $W$5), the highest value is returned and rounded to 2 decimals.

So with both conditions the value in G13 (copied downwards G14, G15 etcetera) is used in the calculation.
With condition $W$8 this is added to the cumulative value in H12 and downwards. And $W$9 is subtracted from this.
With condition $W$5 only $W$6 is subtracted from G13 (and downwards G14, G15 etcetera).
In no case negative values will result. The result will Always be 0 or positive,

I guess the value in $W$6 is associated with the condition in $W$5 and $W$9 is associated with the condition in $W$8.

Well, the word thank you is not enough for you but I have nothing else to say

Let's go back to the formula

What this formula do is it gets two time stamps in 24 hours format and calculates the hourse between them like if we want to calculate the gap between check-in and check-out for a visitor

But it seems super-complicated

Is there any replacement for it that would be simple, easy to understand and do the same job?

Thanks again mr.MarcelBeug

If A1 = time in; B1 = time out, then the formula would be just

If possibly midnight is within the time frame, use

If time gap would be >= 24 hours, you would need to include the date, use the first formula and make sure your result field is formatted as [h]:mm or [h]:mm:ss.

To be honest I really don't recognize this kind of calculation from the original formula, e.g. it doens't make sense to round a time gap on 2 decimals: .01 = 14 minutes and 24 seconds.

Do you know the contents of the fields used in the original formula?

Yeah
actually the person who wrote the formula wants to count the hours only not the hours and minutes
so he want to say that if someone checked in at 17:00 and checked out at 19:30, this person stayed for 2.50 Hours not 2 Hours and 30 Minutes
you get that ?

Well, any time value multiplied by 24 will give you the number of hours if the result field is formatted as a number.

It would make more sense if you share the information what is in the fields mentioned (in column G, H and W).

With all due respect, it feels like being in a quiz now, proceeding for the refrigerator

For a time difference you can just subtract the smaller value from the larger one.....then multiply by 24 to get the hours as a decimal (as Marcel says), e.g. with start time/date in A2 and end time/date in B2 use this formula in C2

=(B2-A2)*24

Format C2 as number

No worries, no bad feeling, I was just joking. "To proceed for the refrigerator" is a common expression in the Netherlands.

It looks like your issue is solved: just use the formula from Barry.

To conclude: if the original formula subtracts time values, then those fields are definitely not formatted as (date/)time, but as numbers.

Well it seems my problem wasn't that bad i feel stupid ??

But it was really nice meeting you guys thanks alot

Special thanks to mr. MarcelBeug

One last thing: can you tell me what that expression mean ?
