# Number in scientific (E) notation (`scientific_notation`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Number written as a mantissa and a power of ten after the letter E, as in 6.022e23. Programming languages, spreadsheets and CSV exports write very large and very small numbers this way. A spreadsheet often turns a long identifier into this form, which loses digits.

- Pattern of: `numeric`
- Personal data (PII): no
- Categories: All measurable values (percentage, amount and e.t.c) (values), Common (common)
- Countries: global
- Languages: Common to most languages (common)

## Detection

Regular expression (Python `re`):

```
^[+-]?\d+(?:\.\d+)?[eE][+-]?\d+$
```

## Examples

- `6.022e23` — Mantissa 6.022 and exponent 23
- `1E-9` — One billionth
- `7.729E+9` — Form that spreadsheets give to a long number
- `6.022x10^23` (invalid example) — Written with a multiplication sign
