Hi folks,
I have little spreadsheet problem and wonder if anyone here can help with
the Eureka side.

In an MS-Win side Excel spreadsheet, I have a function that gives the
number of days between two dates.

Cell C2 contains today date from =TODAY()
Cell D2 contains the date from which the days need to be calculated.

Cell C4 contains the function =DAYS(c2,d2) which does the calculation.
This works okay in Excel, but doesn't work in Eureka.

Is there a comparable function in Eureka that will perform the same action?

Thanks
Dave

Hi Dave

I am by no means a Eureka expert, but as far as I can see the following approach seems to work OK.

Cell A1 - input the date from which the days need to be calculated - dd/mm/yyyy format.
Cell A2 - input the function TODAY() - paste in this function from 'Formula Menu', 'Paste Function' Sub Menu, Category 'Date & Time'.
Cell A3 - input formula "=A1-B1"

I assume that you can juggle how those cells are arranged to suit the rest of your sheet.

Hope that helps (and that this reply lands OK where it should - my first ever post into this forum!)

Cheers

Hi Dave

So sorry - I have just realised that my earlier post contains a major error - sigh!!

Last line should, of course, read: Cell A3 - input formula "=A1-A2".

Sorry about that.

Cheers

Thanks for the thoughts Martyn. :-)

Welcome to this place, and obviously both your postings came through okay.

Though also not an expert, I have been using Eureka since it was first
released in 1992 and it was upon it (Eureka) that much of my old business
was run. Pricing works, accounts, time sheets, etc...

The sheet in question does already exist in both Excel and Eureka and my
aim was to tidy up the formula and functions differences between the two.

The Eureka sheet already works by the method you note, but I was hoping
the "=Days(cell,cell)" or something similar was in Eureka, but obviously
not.

Development work on Eureka ceased in 1995 with a couple of minor tweaks
in 1996 to cope with the arrival of the "Strong Arm Card" in Acorn SARPC
computers.

The "=Days(cell,cell)" does exist in another RISC OS Spreadsheet app,
Fireworkz, but in my now long time retired life, there's no point in
changing to a different app.

Thanks again for the thoughts. :-)

Dave

Nb: Certain formulas I make absolute so they can be copied anywhere in the
sheet.

Eg: =$B$2-$C$2

Hi Dave

So sorry for having (unintentionally) suggested that you might like to try sucking some proverbial eggs - I'm afraid that I hadn't fully grasped from your initial message what it was that you're trying to achieve. Having seen your last message, I realise that you were way ahead of me already as regards the niceties of !Eureka.

Only thing to add is that, having had a quick scan through the !Eureka manual earlier today, I did find mention of a function 'DAYS360', which seems to work and use syntax very much like your Excel one - except that (very bizarrely) it calculates the number of days between two dates on the assumption that a year consists of 12 months of 30 days each!! Definitely no mention of a 'DAYS' function exactly like the one in Excel. Why that should be there but not the precise function that you're looking for is a bit of a mystery - except that I guess it was a whole lot easier to program!

Anyway, good luck with trying to sort out the tidying up of your sheets.

Cheers

Martyn.
I honestly didn't reply from that angle, I just appreciated you taking the
time to make a useful suggestion. :-)

I'm always up for a bit of learning even in my dotage. :-) (Rhenium).
So no eggs were consumed during the chat. :-)

Indeed, that is a really weird function, which I did use in the past with
an added +5 to get a closer answer. =DAYS360(C26,B26)+5 :-(

I do have a copy of the Eureka manual, unfortunately in the past when we
were doing a major redecoration, it was, with a lot of other stuff boxed
up and put in the loft out of the way, but never brought down again...

My oh my, the amount of stuff that gets consigned to the loft in a life
time can be boggling. (Well the married bit of the lifetime).

I'm waffling again... But I must pop up into the loft and bring a few
manuals back down again.

Don't worry Martyn, I'm the leader of that club, having mistaken
Dave's level of questioning so many times we've become good friends
over it!

> Martyn. I honestly didn't reply from that angle, I just appreciated

I used PipeDream for many years - for text, spreadsheets and
databases. It was my workhorse program. (I only started using a BBC B
because I couldn't type accurately, had no secretary and it was better
than Tippex.) [Does anyone remember Tippex?]

I discovered a lot of useful tricks over the years. One, is that if I
use numerical slots,
and put the date into A1 (as 17.3.23) it shows as <17 Mar 2023>
If in A2 I insert A1+7 the slot returns <24 Mar 2023>.
If in A3 I insert A2-A1 the slot returns <7>

Is there no such facility in Eureka?

(At this point, Martyn, I usually discover I've totally misunderstood
the nature of the question.)

I daren't get Pipedream to do the sum. It's nearly +10 years.

Hi Michael, what fun... :-)
Yes, I still have a bottle of Tippex correction fluid here on my office
desk... Mmnn! Come to think about it, I also have a Tippex snail
correction tape, and still use both... :-)

Yes that works the same in Eureka providing you've set the cell to display
a date as "dd mmm yyyy" (Sans quotes).

[Snip]

Michael, you were kind of on the same track as our chat, though we were
specifically noting the lack off, or the inaccurate results of a Function.

But then I'm quite often confused myself, as you know. :-/

The original question was about the function. "=Days(cell,cell)" Which for
some reason does not exist in Eureka.

Followed by a similar but inaccurate function "=DAYS360(C2,B2)" which I
modified to make the inaccurate result a little closer to reality.
"=DAYS360(C2,B2)+5"

This of course can be overcome in Eureka by using the formula...

"=$B$2-$C$2" Where B2 has todays date "=TODAY()" and C2 has the start date
"17 Mar 2022" (Sans quotes).

Anyway, whatever... It's nice to chat with friends.

In Pipedream any numerical slot is a date slot if presented as e.g.
27.3.23

Par for the course then: I didn't grasp the subtleties. In this
instance I plead Covid and being 'with the fairies'. I've already
sent a response today to the wrong person.

Hehe! Do you remember the origins of that joke, I do, but these days one
is not allowed to repeat it in a public space.

That said, very appropriate considering it is St Patrick's day. :-)

Just noticed this question and read through the replies.

Eureka's DAYS360() is odd and inapplicable, and the only method of
extending Eureka's set of functions is by defining a macro:
DAYS(start, end).

Trouble is, simple though such a macro is, it has to be in a separate file
(called, say, 'M', of type &C2E 'EurMacro', preferably alongside sheets
that use it) and those sheets refer to it not by
=DAYS(cell,cell)
but by
=M!DAYS(cell,cell)
(Reference from one sheet to another always involves putting a filename
plus ! before a formula. See pp. B-35 and D-1 in the User Guide).

Such a macro would look like this (in cells A1 to A4):

DAYS
=ARGUMENT("dStart",1
=ARGUMENT("dEnd",1
=RETURN(dEnd-dStart)
