Help: Modulo... not... quite...right...

[Commish]

Hey all good helping people.

I am trying to create a Modulo function to fill out a round/pick
calculation in a draft type spreadsheet.

Specifically, I want the value: 1 to show as 1:1 and the value: 12 to
show as 1:12.

The formula that I have now is: =ROUNDDOWN((P3/12)+1,0)&"/"&MOD(P3,12)

(where the number is in P3)

The formula works fine, until I get to the value of 12, then it
calculates to 2:0 and not 1:12 (which is my goal).

Do I need to add some if/then logic for when the modulo =0, then
subtract one from the 1st part, and set the second part =12? Or is
there a better way?

Nevermind, I'm going with this:

=ROUNDUP(P3/12,0)&":"&IF(MOD(P3,12)=0,12,MOD(P3,12))

You can format the target cell with the following Custom format...

"1:"#

...and just use

=IF(MOD(P3,12)=0,12,MOD(P3,12))

so that the cell contains a usable value which you can use in
calculations and/or in other formulas.

With my suggestion, note that...

If P3=24; Target= 1:12

Using...
=ROUNDUP(P3/12,0)&":"&IF(MOD(P3,12)=0,12,MOD(P3,12))

Target= "2:12"
...which Excel will treat as Time if you try to use it in formulas.

A better way to go might be to use 2 cols so you can use both parts of
your formula in each col:

Example:
A3: =ROUNDUP(P3/12,0)
B3: =IF(MOD(P3,12)=0,12,MOD(P3,12)); Left-Aligned
..where either col can use a custom format to display the colon.

This, then, will now allow you to use the cell values in calculations
and other formulas.
