Python divmod()

Python divmod() function is used to perform division on two input numbers. The numbers should be non-complex and can be written in any format such as decimal, binary, hexadecimal etc.

Python divmod()

Python divmod() syntax is:

Copy
divmod(a, b)

The output is a tuple consisting of their quotient and remainder when using integer division.

For integer arguments, the result is the same as (a // b, a % b).

For floating point numbers the result is (q, a % b), where q is usually (math.floor(a / b), a % b). In any case q * b + a % b is very close to a.

If a % b is non-zero it has the same sign as b, and 0 <= abs(a % b) < abs(b).

Python divmod() example with integers

Copy
# simple example, returns (a // b, a % b) for integers
dm = divmod(10, 3)
print(dm)

x, y = divmod(10, 3)
print(x)
print(y)

dm = divmod(0xF, 0xF)  # hexadecimal
print(dm)

Output:

Copy
(3, 1)
3
1
(1, 0)

Python divmod() example with floats

Copy
# floats, returns usually (math.floor(a / b), a % b)
dm = divmod(10.3, 3)
print(dm)

dm = divmod(11.51, 3)
print(dm)

dm = divmod(-11.51, 3)
print(dm)

Output:

Copy
(3.0, 1.3000000000000007)
(3.0, 2.51)
(-4.0, 0.4900000000000002)

Notice that in case of floating points, the q * b + a % b is very close to a in some cases.

divmod() with complex numbers

If we pass complex numbers as argument, we will get TypeError.

Copy
dm = divmod(3 + 2J, 3)

Output: TypeError: can't take floor or mod of complex number.
