Amateur user of Excel/Calc/Google sheets here. My worst is...

    =CONCATENATE(
        IF(A1<0;"-";"+");
        TEXT(INT(ABS(A1));"00") ;"d";   
        IF((ABS(A1) - INT(ABS(A1)) - INT( (ABS(A1) - INT(ABS(A1)))*60 )/60) * 3600 > 59.5;
            TEXT(INT((ABS(A1) - INT(ABS(A1)))*60)+1;"00");
            TEXT(INT((ABS(A1) - INT(ABS(A1)))*60);"00")
        );"m";
        IF((ABS(A1) - INT(ABS(A1)) - INT( (ABS(A1) - INT(ABS(A1)))*60 )/60) *   3600 > 59.5;
    TEXT(0;"00");
            TEXT(ROUND(    (ABS(A1)-INT(ABS(A1))-INT((ABS(A1)-  INT(ABS(A1)))*60)/60)*3600;0    );"00")
        );"s" 
    )

...which should take a value in cell A1 that is in the range [0,360) and return the value in angle notation (degrees, minutes and seconds). I especially wanted this function all in one cell to save loads of helper cells (the spreadsheet calculates the position of the moon, sun, planets and a physical ephemeris for each planet so a lot of angles to display).

It is a pain to apply, I use a text editor to search and replace the cell reference for each angle. I'd settle for the formula bar display of the formula not reformatting the line breaks.

In Excel you could use =LET(a; A1; ...) to define a variable 'a' local to the formula. You would have to change A1 in one place only.

I'm not sure this works with LibreOffice though. Probably not.

I feel you can do something with floor and trunc to get the remainder, then using round to get the sig figs correct. You can make it abs of it at the start, and then only add a negative at the start of the concat if it's negative.

I rapidly tried and I get something a bit shorter (about half the length), but my rounding ends up with imperfect precision and sometimes I get 10m60s rather than 11m0s due to it. Appropriate rounding at the appropriate points would fix that.

You could put that into a VBA formula, although it wouldn't be as fast unfortunately (as I learned when I tried simplifying excel formulae - which are _compiled_ whereas VBA I think is interpreted? - in any case, excel was like 50x faster for me).

I assume you have tried the '$' signs to see if they will help?

Thanks for reply. Yes, if it was just for Excel I'd make a user defined function that returned a text value. I wanted the formula to work the same on Libre/Open office and on Google sheets so I went for an actual spreadsheet formula. Actually, the ';' separator came from the LibreOffice version.

'$' signs for A1? I'd still need to search and replace for A1 each time I needed to convert an angle in a different cell but I take your point that I could move the output around more easily. Speed does not seem to be an issue (the rest of the spreadsheet has calls to trig functions by the score)

Not sure about the cross compatibility to Libre and Google, but in Excel at least, replace your cell references with INDIRECT() references. Then store the cell you want to calculate on in another cell…say A1 (literally just type C1 in A1). Then reference with INDIRECT(“&$A$1&”). Saves you the search and replace for A1. Also works great if you want to copy formulas across tons of columns and maintain the correct column header references as you can insert the INDIRECT reference into table notation.

[leipert]

If you prepend the column/row with a dollar, it is locked when you drag and extend.

e.g. $A1 locks the column, A$1 the row and $A$1 both

Can be pretty helpful if you put a constant somewhere.

Thanks for your reply. I am aware of the absolute cell reference notation and use it frequently when I have a set of constants (e.g. longitude, latitude, year, month, day, timezone &c) that are referenced in many formulas. However the situation in my post was the other way round sort of.

As a concrete example (just in case I've mis-understood the situation), I have the right ascension, declination and phase angle of Venus as decimal angles in cells G80, H80 and M80 and I want the output strings in cells F3, G3 and H3. I still need to search and replace the A1 cell reference in my original post for each of the formulas.

As the poster a couple levels above pointed out I could do this as a user defined function in VBA, but I wanted my daft spreadsheet to work on Libre/Open office and on Google sheets with little or no modification. Hence the chain of if statements and round() functions.

I can't imagine how much time this one thing would have saved over my last 40 years of spreadsheeting.
