Or if you wanna mess with math you can calculate the values using 10^(x/E) where E is the number of the tolerance family (i.e 24, 48 etc) and x is 0 to the max value of E. Then multiply the result by the decade of resistance (10,100,1k,etc).

I had to use this in a program I wrote once to calculate a bunch of network values or some parameteric sweep something or other. I believe this also works for inductors but not capacitors.

I use this formula in spreadsheets to round values to E96.

This following calculates the E96 value of the contents of cell "E8".

=IF(E8<(ROUND(10^(INT(96*LOG10(E8))/96),2-INT(LOG10(E8)))+ROUND(10^(INT(96*LOG10(E8)+1)/96),2-INT(LOG10(E8))))/2,ROUND(10^(INT(96*LOG10(E8))/96),2-INT(LOG10(E8))),ROUND(10^(INT(96*LOG10(E8)+1)/96),2-INT(LOG10(E8))))

I forget the source for this formula - I used it in the THAT1510 gain spreadsheet here: https://proaudiodesignforum.com/forum/p ... 142&p=1160

That's a long formula. My eyes bled halfway through it. I was first introduced to the calculation by an Engineer when I was still plodding through my EE classes in college as a "did you know" moment.

This site shows my explanation but explains it a bit better: https://www.rfcafe.com/references/elect ... values.htm

That's why I always copy and paste that one.
