<table><thead><tr><th width="161">Function Name</th><th>Description</th></tr></thead><tbody><tr><td>abs</td><td>Returns the absolute value of a number. The absolute value of a number is the number without its sign.</td></tr><tr><td>sqrt</td><td>Returns the square root of a positive number.</td></tr><tr><td>pow</td><td>Returns a number raised to a power. Takes two arguments: the base number and the exponent.</td></tr><tr><td>exp</td><td>Returns "e" raised to the power of a number. Takes one argument, the exponent.</td></tr><tr><td>log</td><td>Returns the logarithm of a number to the specified base. Takes two arguments: the number and the base. The default base is 10.</td></tr><tr><td>ln</td><td>Returns the natural logarithm of a number. Takes one argument, the number.</td></tr><tr><td>round</td><td>Rounds a number to the nearest integer.</td></tr><tr><td>floor</td><td>Rounds a number down to the nearest multiple of a significance value. Takes two arguments: the number and the significance.</td></tr><tr><td>ceil</td><td>Rounds a number up to the nearest multiple of a significance value. Takes two arguments: the number and the significance.</td></tr><tr><td>sin</td><td>Returns the sine of an angle.

# Agent Instructions: 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:

```
GET https://docs.enji.io/intro/learn-enji.io/built-in-functions.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
