Python’s modulo operator (%) always return a number having the same sign as the denominator (divisor). So Python modulo negative numbers will be a positive number if the denominator positive number.
Python applies the distribute law of the Modulo operator which is:
(a+b)mod n = [(a mod n)+(b mod n)]mod n
Math calculation
-5%4 = (-2*4 + 3) % 4 = 3
Python modulo negative numbers example
Simple example code using negative modulo.
res1 = -5 % 4
res2 = ((-2 * 4) + 3) % 4
print(res1)
print(res2)
res = -5 % -4
print(res)
