# LogExpMath

Provides high-precision mathematical functions for logarithmic and exponential operations, which are crucial in many DeFi reward calculations (e.g., bonding curves, APY adjustments, dynamic pricing). Solidity lacks native high-precision log/exp functions, so this library ensures safe and accurate computations.

Exponentiation and logarithm functions for 18 decimal fixed point numbers (both base and exponent/argument). Exponentiation and logarithm with arbitrary bases (x^y and log\_x(y)) are implemented by conversion to natural. Exponentiation and logarithm (where the base is Euler's number).

## 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://gitbook.mor.org/smart-contracts/documentation/distribution-protocol/v7-protocol/contracts/libs/logexpmath.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.
