Number Base Converter by langbot-team

# Number Base Converter

Convert integers between any bases 2-36. Zero dependencies (pure stdlib).

```
python scripts/run.py ff --from-base 16 --to-base 10
python scripts/run.py 255 --to-base 2
python scripts/run.py 1010 --from-base 2 --to-base 16 --prefix
python scripts/run.py 255 --all
echo "10 20 30" | python scripts/run.py - --to-base 16
```

Supports an optional sign, `_` separators, and 0x/0o/0b prefixes on input.

# Number Base Converter

Convert integers between arbitrary bases (2-36) from chat.

## When to use
The user has a number in one base and wants it in another — hex to decimal, binary to hex, decimal to base-36, etc. — or wants to see binary/octal/decimal/hex all at once.

## How to use
Run `scripts/run.py` with the number plus `--from-base`/`--to-base`:
- `python scripts/run.py ff --from-base 16 --to-base 10` — hex `ff` to decimal.
- `python scripts/run.py 255 --to-base 2` — decimal 255 to binary.
- `python scripts/run.py 1010 --from-base 2 --to-base 16 --prefix` — binary to `0xa`.
- `python scripts/run.py 255 --all` — show bin/oct/dec/hex.
- `echo "10 20 30" | python scripts/run.py - --to-base 16` — convert many via stdin.

Default from-base is 10, default to-base is 16. Underscores and 0x/0o/0b prefixes in input are tolerated.

## Pitfalls
- Integers only — no fractions or floats.
- Digits must be valid for the input base (e.g. `2` is invalid in base 2); invalid digits exit 1.
- Bases outside 2..36 exit 2.
