Odd word use

Do they really call exponents "suffixes" where you're from? I've never heard that usage before.

suffixes

They probably don't but I did. The goal of this series is to communicate via audio the location of the symbol.

Although looking at the definition it's not a bad word to use.

https://www.thefreedictionary.com/Suffixes.htm

Suffixes are morphemes (specific groups of letters with particular semantic meaning) that are added onto the end of root words to change their meaning. Suffixes are one of the two predominant kinds of affixes—the other kind is prefixes, which come at the beginning of a root word.

Great reminder

Thanks, Ken.

I have been using these prefixes for decades, and take them for granted. Thanks for the reminder that this is not common knowledge.

It also reminds me of a question for which I have never found a good answer. In North America, capacitance, is expressed in uF (micro Farads) or pF (pico Farads). But nF (nano Farads) is not used. Instead you will see values like 10,000 pF or 0.01 uF.

Go figure.
