The function logaddexp() of numpy in Python returns the logarithm of the sum of exponentiations of x1 and x2 inputs in base-2.
It can be expressed mathematically as:
logaddexp(x1, x2) = log2( + )
logaddexp2(x1, x2, out)
The logaddexp2() function takes the following parameter values:
x1, x2: This represents the input arrays or scalers.out: This represents a location where the result is stored. This is optional.The logaddexp2() function returns the logarithm of the sum of the exponentiations of x1 and x2 in base-2.
from numpy import logaddexp2# creating our input valuesx = 2y = 3# calling the logaddexp2() functionmyresult = logaddexp2(x, y)print(myresult)
logaddexp2 from numpy module.x and y.logaddexp2() function on the variables x and y. The result is assigned to a variable myresult.myresult.The function logaddexp2()  is useful in statistics, especially when the probability of an event is so tiny that it exceeds the range of regular floating-point numbers. In such cases, the logarithm of the calculated probability is stored. The function allows storing the added probabilities in such a fashion.
