How come Bucherer is generally un-loved?

Decimalization is one of the worst things to happen to the UK. Base 980 does not require the need for fractional math. It also allivieates rounding errors. I always wondered in Davic Copperfield, Steerforth could divide the take between 3 or 4 conspirators evenly and fairly.
Mr Micawber gives the answer.
20 shillings to the pound and 12 pence to the shilling. A pence could be divided into 4 farthings.

A lot of the touristy places when I went in 1984 sold the old pre decimal currency. When I went in 1999 I got a 20 pound note with DIckens on the face as a souvenir. Sadly the purse I kept it in was stolen one 4th of July when I left the purse on the trunk (boot) of my car when unlocking it. In the family driveway.

I noticed that currency and coins in Europe expires after a while. US script so far since some point in time after the American civil war never expires. Before that time Banks printed their own script. Coinage has different rules. I think between the 1930s and the 1970s one could not own gold over a certain weight in the US.

Now everything is in euros. Although Britton only went part way back. Globalization has come a long way.

Now how many watches could 980 farthings purchase? Or would I get a better deal if it was 120 pence? A farthing bought a loaf of bread or a pint of beer.

Non linear mathematics are weird. That is a world where returns of 3 percent can not be calculated by shifting the decimal to 30 percent. Although many have tried.

Still I learned something else today. What was true yesterday or 60 years ago is no longer true today.

My finger must have slipped.
The reason for not going to metric (Which Tho Jefferson made the standard way back when) Has to do with the same reasons time and pre decimal UK currency took so long. The French actually tried decimal time. Rounding errors. Thirds and sixths are repeating fractions. Even an 8th and 3/16ths are awkward numbers in decimal systems.

Fractions in base 10 are not all that intuative. (I failed basic math in grade school. But I could read Sherlock Holmes books) Give a semi skilled person a ruler which maps to base 12 and it is easy to work things out empirically.

I have a book on rounding errors in single precision math. The old words had a 24 bit (I think it was called mantisa) and 7 bits for the exponent and 1 bit for the sign. to fit into 32 bits. So there are only 16 million numbers what could be represented before rounding errors creap in for any given block of 128 decimal shifts. 2,147,483,648 is the number I calculated 2^31.

The old iron used BCD (Binary coded decimal.) like a calculator which could extend the arrays. Some early computers did this as well. But floating point was quicker and took up less storage. The first basic was from processor tech, which had 4 Bit BCD. When I got to the time share basic programs did not work the same.

Time keeping can have similar issues. Not only was I bad at math in grade school I could not tell time. Even now I look for that hour between 7:59 and 8' oclock. Most people can not tell 12 AM from 12PM. Why Midnight and Noon are used. I sometimes work security and it takes a moment to figure out what day 00:00 is. Not the only one that has shown up 24 hours early, or called a replacement who says their shift is tomorrow.

Clock dials show relational time. I did get a watch when little. May still have it. I could also see on the clocks how much time there was till the end of class. But going from what the hands said, to what the words were eluded me, Until the 1970s and decimal displays and watches became popular.

Time (and highway speed.) is also perceptive. I always loved Einsteins thought experiment. That sitting on a hot stove seems to take longer than kissing a pretty girl. This may have explained the burn marks on his shirt tails and the seat of his pants.

Most US rulers have both Imperial and metric. A lot of us use which ever scale fits what we want to measure without having to use fractional notation. Not the best way to land a spacecraft on Mars though.

Twice a year when I reset the clock on my car, I tend to get the speedometer set to KPH.

Was surprised when I drove in England in the 1990s that the distances were all marked in miles.

Now how many furlongs per fortnight is that?
