TypeError: unsupported operand type(s) for /: 'float' and 'Bicomplex'

The following gives an error:

import numpy as np
import numdifftools as nd

g = lambda x: 1.0/(np.exp(x[0]) + np.cos(x[1]) + 10)

print(nd.Gradient(g, method="multicomplex")([1.0, 2.0]))

If I change the method to "complex", it works fine. Is there a way to use the multicomplex method in this situation and other similar ones?

I don't get this error:

Python 2.7.14 |Anaconda custom (64-bit)| (default, Oct 15 2017, 03:34:40) [MSC v.1500 64 bit (AMD64)]

In [10]: nd.Gradient(g, method="multicomplex")([1.0, 2.0]) 
Out[10]: array([-0.01796112,  0.00600821])

What version of numdifftools and python are you using?

[bacalfa]

I'm on Windows 7 64-bit.

Python 3.6.5 :: Anaconda custom (64-bit)

numdifftools=0.9.20=py_0

Fixed in commit [481caaf] (481caaf).
