# 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.
