I have a one dimensional numpy array for which I need to find out if any value is zero or very close to it. With this line I can check for zeros rapidly: if 0. in my_array: # do something but I also have very small elements like 1.e-22 which I would also like to treat as zeros (otherwise I get a Divide by zero warning further down the road) Say my threshold is 1.e-6 and I want to efficiently check if any value in my array is smaller than that. How can I do this? Continue reading...
