Since it means "10^e", the "e" is "functionally" at the end but it might not appear to be since the exponent can be any number e.g 1.2e-334556.232564264 (which means 1.2*10^-334........) The "e" itself is sometimes instead written "E" (maybe because old calculators can't easily show "e"). That the exponent can also contain a varied set of characters. In reality it can be any number of characters because they can be variables with arbitrary names but the common cases are limited. While my math knowledge is both limited and rusty, I'd say these are necessary to manage: - minus character e.g 1.2e-3 - decimal period e.g 1.2e3.4 - division character as in 1.2e3/4 I would think one can also write 1.2e.3 meaning 1.2e0.3. Of course, in many parts of Europe we write 1.2e0,3 (comma instead of period). Beyond this maybe parentheses and constants like pi. There can also be other bases than 10 which, if memory serves (and it might not), is notated with a subindex on the e. This is not totally fringe but definitely "university level". <:-) P.S What is that noise? Is that Josiah screaming curses, pulling his hair and smashing his computer? Easy my friend, no need to cover it all. ;-) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
