Scientific Notation Truncation
 

How do I truncate a number in scientific notation without rounding the last
number?

example:
D22: 7.20117 E12 and I want 7.2011(0) E12

I have tried =TRUNC(D22,4) with no success. I am fairly new at excel so
very detailed responses are welcome. Thank you!

Try...

=TRUNC(D22*10000)/10000

Hope this helps!

How about =TRUNC(D22/1000000000000,4)*1000000000000
Enter it as =TRUNC(D22/1E12,4)*1E12

Or for the more general case
=TRUNC(D22/10^INT(LOG(D22)),4)*10^INT(LOG(D22))

Have you tried that, Domenic?
D2*10000 is 7.20117E16, so the TRUNC doesn't help.

If you really have 7.20117 E12 in a cell in Excel, then it must be text. So apart from text manipulation you can't do this.
Even text manipulation followed by conversion to number would not get you any further than 7.2E12, because of Excel's maximum
precision of 15 decimal digits.
To be fair, it's not an Excel limitation, it's a limitation of the IEEE floating point standard.
