A038528: If n has decimal expansion abc...d, with k digits, let f(n) be obtained by deleting all k's from abc...d, closing up and deleting initial 0's; sequence gives n such that f(f(f(...(n)))) = 0 or empty

This is more of a repository, but it is one I am quite happy with. The idea behind this was a set of improvements to the , mostly by adding more , including both and . It expands from the unit to include units such as Megameter, Gigameter, Terameter, etc. and Mebimeter, Gibimeter, Tibimeter, etc.

The Denga, a coin from Russia, issued since at least the mid 14th century. In 1535, was the first country to go with the Denga worth 1/100 Rubles. I found an argument that they continued to also use non-decimal until after 1800 but I can't find references for that? Any help? Meanwhile, here is a Denga from 1749, issued under Elizaveta Petrovna.

:python: Hey! There is an awesome `decimal` package in Python standard library.

💡 Imagine, you can have an alternative third-party Decimal implementation in Python that would be 5x faster. It will be especially faster to parse from JSON or a string and faster to serialize.

❓ The only catch is you can have only essential features in this implementation. What those features would be?

It amuses me that people spend time practicing to recite the transcendental number to hundreds of digits, or asking computers to compute billions of decimal digits, but only works with 16 significant figures.

There are 203 where one digit is the sum or product of the other two. Only 148 if no zeros are allowed.

[OP birdsite 20131026]

2023 bonus: Ironically, neither 203 or 148 are members of that set.

Funny story. Yesterday I went into the farm shop in Dawlish, just before closing. Walked round, looking for eggs and had to ask because they'd been moved into the back room. 'How many do you want?' asked the teenager serving. 'Oh, I'll take a dozen,' I said. She replied . . . .

.

.

.

.

'Is that six or twelve?'

I'm going to write to Jacob Rees-Mogg about this.

@coolo nor in any language using Floating Point arithmetic! It's a common gotcha.

It *can* be true in Python - use exact decimals, or compare floats the right way (for "closeness").

```
from decimal import Decimal
Decimal(0.1) + Decimal(0.2) == Decimal(0.3) # True
```

docs.python.org/3/library/deci

Or use `isclose` from `math` or `cmath`, as of 3.5:

```
from math import isclose
isclose(0.1 + 0.2, 0.3) # True
```
