Hello everyone.
I am starting to do self-study the IEEE 1584:2018 standard for arc-flash calculation.
During the reading of the data from Table 2 Coefficient for Equation (2), I found there is different written of wording.
For. e.g, for K2 factor:
"−6.0287E-05" for VCBB is described and "−3.097e-06" for HCB is used.
My question is for "e" in the table data sheet is it just mistake which shall be to "E" instead? for e.g, "−3.097e-06" corrected to "−3.097E-06" = "-3.097x10-6".or,
there is different meaning for "e", for e.g, "natural logarithm"?
Thanks for your help.

I believe that is a typo since these are all coefficients in scientific notation.
It has been added to the list for next time.
Thanks!
