savetxt How change the type from float64 to int or double

You can define how the output has to be formatted with the fmt parameter of np.savetxt, e.g.:

for floats rounded to five decimals:

  np.savetxt("file.txt", output, fmt='%10.5f', delimiter='\t')

for integers:

  np.savetxt("file.txt", output, fmt='%i', delimiter='\t')

Here you can find more information about the possibilities of fmt:

http://docs.scipy.org/doc/numpy/reference/generated/numpy.savetxt.html

In case you want to specify the number of decimals in the float the

np.savetxt("file.txt", output, fmt='%10.5f', delimiter='\t')

7 decimals in this case

np.savetxt("file.txt", output, fmt='%10.7f', delimiter='\t')

Basically, fmt = %10.Yf' where Y specifies the number of decs.
