Hello,

I don't only need a human readable representation of number, I need to use it further, do things such as putting it in a pandas object and saving it to an excel file.

Doing things such as 
x="{0:10.5f}".format(x)
gives a str object as a result:
<built-in method format of str object at 0x07F84A48>
