OK
Thanks Mike smiley-wink

I was stuck on thinking round up was rounding down...
If you realize i have written it in the first post, but whatever...

Now i understand it, round up to prevent overlap, ok

In the 3.3 case, where you have 3.16 if you round up to 3.2 it is still overlaping so you keep adding 0.1 until you prevent it, is that correct?

What do you mean by rounding up two places? Using the 4 and 6 only?
But how do you get the 7?

Thanks

Yep, I saw it a bit late, seems that the formula gives numbers that should be aproximated to Renard ones or something similar

I will get the E6 and E48 as a base and build the rest

Thanks for the answer

Seeming that no one in the Spanish forum has the knowledge to answer this question I will post it here

To get the resistor scales (E12, E24, E48...) you use the following formula:

10^(i/n)

Where n is the scale number (12,24,48...) and n is a natural number from 0 to n

The problem is that when getting the E12 resistor values, the first ones come ok, but when arriving to higher values like 4.7 Ohms, the formula gives 4.64 so even with rounding you can't get the 4.7 value

Rounding up isn't valid as for 3.3 it gives 3.16

Anybody knows why?

Have you tried asking Wolphram about it?

I answered all of them, but failed one... 87$ to spend. now the hard part, what to buy
