The Intracices of the Python Modulo Operator

Modulating the Modulator

Divisor larger than dividend:

• 5%2=1
• 158%100=58

Divisor smaller than dividend:

• 2%5=2
• 100%158=100

Negative divisor (in Python, the remainder must always be positive):

• -18%100=82
• -188%100=100

Handy template expression to use: divisor = ? * dividend + remainder, where ? is the number of times the dividend fits into the divisor. - 158%100: 158 = ? * 100 + remainder - -18%100: -18 = ? * 100 + remainder - In Python, the remainder must always be positive. Thus, ? in this case is -1.
