Rounds to the next lowest integer. The fractional part of a number is dropped, so the value is pushed down to the whole number below it and `4.9` becomes `4`. A number that is already whole stays the same. Use this when you must always round down, for example working out how many complete bundles fit into an available quantity.

## Fields

This mapper has no settings to configure. Point it at the number you want to round and it does the rest.

## Sample data

| Field         | Value |
| ------------- | ----- |
| (no settings) |       |

Input:

```json theme={null}
{
    "weight": 4.9
}
```

Output:

```json theme={null}
{
    "weight": 4
}
```

```json Configuration theme={null}
{
  "prototype": "math-floor",
  "parameters": {}
}
```
