# LaTeX-fejl: Ukendt float-indstilling \`H'

Denne fejl vises, når du har glemt at indlæse **`float`** pakken. Flydeangivelser skrives i de kantede parenteser, hver gang vi bruger en *float* såsom en figur eller en tabel, dvs. den **`H`** i **`\begin{figure}[H]`**. **`H`** flydeangivelse er en del af pakken. **`float`** pakken. Den fortæller compileren, at figuren skal placeres præcis på den pågældende placering på siden i stedet for at flytte den et andet sted hen. Når vi vil bruge denne mulighed, skal vi inkludere **`\usepackage{float}`** i vores præambel. For at læse mere om, hvordan man bruger muligheder til at angive flydepositioner, så se vores [dokumentationen](/latex/da/figurer-og-tabeller/02-positioning-images-and-tables.md).

## Almindelige årsager

**At glemme at indlæse `float` pakken:**

Den [float-pakken](https://www.ctan.org/pkg/float?lang=en) giver os `H` mulighed. Dette er en stærkere version af `h`og fortæller LaTeX, at vi gerne vil have, at figuren skal vises *præcist* her. Hvis vi bruger `H` muligheden, men glemmer at inkludere `\usepackage{float}` i vores præambel, får vi en fejl som den, der vises nedenfor

main.tex, linje 12

LaTeX-fejl: Ukendt flydeoption \`H'.

Se LaTeX-manualen eller LaTeX Companion for en forklaring. Skriv H for øjeblikkelig hjælp. ... l.10 \begin{figure}\[H] Option \`H' ignoreres, og \`p' bruges.

For at løse denne fejl skal vi blot inkludere **`\usepackage{float}`** i vores dokumentpræambel, dvs. før **`\begin{document}`**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/da/latex-fejl/19-latex-error-unknown-float-option-h.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
