I created a 10x10 array that serves as a multiplication table. I wanted to use conditional formatting to easily highlight all the perfect squares (e.g. 4,16,25,36...)
Is there anyway I can do this by entering in a formula into conditional formatting? I have a basic idea of how I could do this-- =B2=POWER(SQRT(B2),2)... I am confused on how I could do this in conditional formatting formulas.
Any ideas?
If the array is in A1:J10 (the array that I used) Select the array and click on Conditional Formatting, New Rule, Use Formula...., and enter this formula in the formula field.
Formula:
=OR(MOD(SQRT(A1),2)=0,MOD(SQRT(A1),2)=1)
Select the formatting that you want to apply.

I think that would highlight all numbers because any number is the same as the square of it's square root, perfect square or notOriginally Posted by Yobish
Try
=MOD(B2^(1/2),1)=0
although that will also format blanks so if you don't want that change to this version
=(B2<>"")*(MOD(B2^(1/2),1)=0)
Audere est facere
Try it. I used whole numbers only.
Thank you! I had been working on it for way too long-- now I am relieved.
