How to fix the ZeroDivisionError with 1000 decimals digits output in Python? Question: In the following 2 examples: Example 1: from decimal import Decimal, getcontext getcontext().prec = 1000 d = Decimal(1+10**(-24)) 1/d.ln() Example 2: from mpmath import * mp.dps = 1000 mp.pretty=True 1/(ln(1+10**(-24))) I get the ZeroDivisionError. Python 3.7(64-bit) takes it as 1/ln(1) or 1/0. …
Ignore divide by 0 warning in NumPy Question: I have a function for statistic issues: import numpy as np from scipy.special import gamma as Gamma def Foo(xdata): … return x1 * ( ( #R is a numpy vector ( ((R – x2)/beta) ** (x3 -1) ) * ( np.exp( – ((R – x2) / x4) …
How to return 0 with divide by zero Question: I’m trying to perform an element wise divide in python, but if a zero is encountered, I need the quotient to just be zero. For example: array1 = np.array([0, 1, 2]) array2 = np.array([0, 1, 1]) array1 / array2 # should be np.array([0, 1, 2]) I …
How do I catch a numpy warning like it's an exception (not just for testing)? Question: I have to make a Lagrange polynomial in Python for a project I’m doing. I’m doing a barycentric style one to avoid using an explicit for-loop as opposed to a Newton’s divided difference style one. The problem I have …
