A command-line wrapper around [mpmath's

identify](http://docs.sympy.org/0.7.1/modules/mpmath/identification.html#identify).

You come across the number 0.866025. It looks vaguely familiar but you can't quite point

your finger at it? Then identinum is for you.

identinum is a small command-line utility that "de-decimalizes" decimal numbers into

approximate rational expressions (with some basic functions).

```

$ identinum 0.4285714285

3/7   -7.14285297576112E-11

```

```

$ identinum 0.866025403

sqrt(3)/2   -7.84438675343059E-10

```

Index](https://pypi.org/project/identinum/), so simply do
