How to force a ndarray show in normal way instead of scientific notation?

Question

I\'m trying to print a ndarray on the screen. But python always shows it in scientific notation, which I don\'t like. For a scalar we can use

>>> p         


        

Answer 1

The numpy.set_string_function function can be used to change the string representation of arrays.

You can also use numpy.set_print_options to change the precision used by default and turn off reporting of small numbers in scientific notation.

From the examples for set_print_options:

>>> np.set_printoptions(precision=4)
>>> print np.array([1.123456789])
[ 1.1235]

Answer 2

I don't know about the numpy arrays but I was simply facing the same problem while doing a project in Python.

Take a look at the Decimal class provided http://docs.python.org/library/decimal.html .

I don't know if it's provided in numpy though.
