# Bedingungen

In Soulver wird eine Bedingung in einer einzigen Zeile ausgedrückt:

```
earnings = $45k                                 | $45,000.00

if earnings > $30k then tax = 20% else tax = 5% | 20%

My tax paid: earnings × tax                     | $9,000.00
```

**Deklarieren einer Variable mithilfe einer Bedingung**

```
income = $35k
expenses = $21.5k

profitable = true if income > expenses     | true
insolvent = false unless expenses > income | false
```

**Verwendung von „und“ und „oder“ in Bedingungen**

```
BMI = 24
Underweight = BMI < 18.5                  | false
Healthy Weight = BMI >= 18.5 and BMI < 25 | true
Overweight = BMI >= 25 and BMI < 30       | false
Obese = BMI >= 30                         | false
```

#### Vergleichsoperatoren & boolesche Werte

Soulver unterstützt standardmäßige ["C"-Stil](https://en.wikipedia.org/wiki/C_\(programming_language\)) Vergleichsoperatoren.

Es wird ein boolescher Wert (`true` oder `false`) zurückgegeben.

| Name                | Operator |
| ------------------- | -------- |
| Gleich              | ==       |
| Ungleich            | !=       |
| Größer als          | >        |
| Kleiner als         | <        |
| Größer oder gleich  | >=       |
| Kleiner oder gleich | <=       |

Sie können einer Variablen direkt einen booleschen Wert zuweisen

```
cost = $500                                 
discount = true                        
if discount then cost = cost - 10%
cost | $450.00
```

Sie können Vergleichsoperatoren auch außerhalb von if-Anweisungen verwenden

```
20km == 20,000 m   | true
11:30 am < 9:30 am | false
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://documentation.soulver.app/de/syntax-referenz/general/conditionals-and-comparisons.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.
