# ToggleLeadingZeroes

## Description

Toggle leading zeroes.

This command displays or hides the leading zeroes of the current operand. Example: if the instruction looked like this:

```
    and     ecx, 40h
```

then after applying the command it will look like this:

```
    and     ecx, 00000040h
```

If you prefer to see leading zeroes in all cases, then open the calculator and enter the following expression: [set\_inf\_attr](https://idc.docs.hex-rays.com/inf_attr.html) (INF\_GENFLAGS, get\_inf\_attr(INF\_GENFLAGS) | INFFL\_LZERO); This will toggle the default for the current database and all numbers without leading zeroes will become numbers with leading zeroes, and vice versa.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.hex-rays.com/ida-9.5/ida-actions/toggleleadingzeroes.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
