There's no reason you can't have 400 degrees in a circle and therefore 100 for a right angle.

It's a degree scale: you can choose any number you want.

The Indiana pi bill mandated certain mathematical values be changed to the wrong value.

Whenever I'm late to a meeting I blame it on the french revolutionary calendar.

Some pocket calculators from not too long ago supported this unit for some reason, along with radians and degrees. That's the third option on "DRG" button.

It used to be that they gave you the choice. You could round or you could use pennies but you had to be consistent throughout the return, because even the IRS doesn’t care if you manage to scrape out 49 cents.

Has that changed and it has to be dollars now?

I'm not really sure about "He said it was to reduce [...] criminals having to store it". Storage shouldn't be a huge problem - IIRC you can pack about a hundred million onto a standard pallet. Even for Escobar, who is THE outlier here, and assuming he's holding 100% of it in cash, that's about 300 pallets which easily fits into a normal warehouse. If you've got that much money it shouldn't be impossible to keep a warehouse like that clean and dry.

Now, "illicit activity" more broadly speaking checks out to me. The EU stopped printing the 500 euro note because it was primarily used for illegal transactions and money laundering.

When the $1000 bill was retired, a loaf of bread cost a couple cents. There was indeed a push to purge them during the drug scares of the late 20th century. A suitcase of $1000 bills is far sexier than one of $100 bills. It really was porting them.

With bitcoin, it's moot.

A $100 is basically a tank of gas and a sandwich in CA.

The 500-euro bill is being phased out for similar reasons. Though it's worth noting a 100-dollar bill was worth more than twice what it is today when Pablo Escobar died.

I'm pretty sure the OP was talking about a far future where a $100 bill is worth less than the current penny

Profit for the US government. Fixed by plastic bills.

Every $ printed but never redeemed is a significant profit (assuming other costs are low like printing).

Especially yummy when countries just want to hoard the currency - same as selling stamps that are never used:

  estimate the stock of U.S. currency circulating in Argentina ... U.S. currency inflows during 1988-1992 totaled $20.8 billion

Though I think the parent means, eventually in the (hopefully) distant future, we'll get rid of the $100 bill because it will be worth too little.

The other thing about hundred is I tend to carry one or two when I travel internationally but I’d never count of using one in a lot of places in the US.

We can revisit our notion of the passage of time when we achieve extra planetary life
