The [json](https://docs.python.org/3/library/json.html) module in the Python standard

library does not allow you to specify the format in which `float`s are written out the

file. This module adds the `float_format` parameter.

```python

import math

import fjson

data = {"a": 1, "b": math.pi}

string = fjson.dumps(data, float_format=".6e", indent=2, separators=(", ", ": "))

print(string)

```

```json

{

  "a": 1,

  "b": 3.141593e+00

}

```
