Compute the logarithm base n with scimath in Python
To compute the logarithm of a number with a base n using scimath from numpy, you can use the change of base formula:
logn(x)=log(n)log(x)
Where \log(x) can be any logarithm (natural log, log base 10, etc.).
Here's how you can compute the logarithm base n using scimath from numpy:
import numpy as np def log_base_n(x, n): return np.scimath.log(x) / np.scimath.log(n) # Example usage x = -100 n = 3 result = log_base_n(x, n) print(result)
In this code, we use np.scimath.log() which calculates the natural logarithm (base e). For the base n logarithm, we apply the change of base formula.
