JSON with float formatting.

The json module in the Python standard library does not allow you to specify the format in which floats are written out the file. This module adds the float_format parameter.

import math
import fjson


data = {"a": 1, "b": math.pi}
string = fjson.dumps(data, float_format=".6e", indent=2, separators=(", ", ": "))
print(string)

{
  "a": 1,
  "b": 3.141593e+00
}
