E-Values derived from a geometric sequence formula by Charles Renard were already accepted and widely used before the ISO recommendation no.

3 has been published. For this historical reason, rounding rules of some values are sometimes irregular. Although all E-Values could be calculated at runtime, we initialize them in a lookup table what seems the most easy way to consider any inconvenient irregular rules. Same table is also used to lookup non calculable but readable BOM value strings. Supported E-series are:

• the calcuation time can be very high for series > E24
