Divmod (a, B) Function

Chinese description:

The divmod (a, B) method returns a // B (Division) and the remainder of a to B.

The returned result type is tuple.

Parameters:

A and B can be numbers (including plural numbers)

Version:

Complex numbers cannot be processed before python2.3.

English description:

Take two (non complex) numbers as arguments and return a pair of numbers consisting of their quotient and remainder when using long division. with mixed operand types, the rules for binary arithmetic operators apply. for plain and long integers, 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) but may be 1 less than that. 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 ).

Changed in version 2.3: Using divmod () with complex numbers is deprecated.

Python code example:

>>> divmod(9,2)(4, 1)>>> divmod(11,3)(3, 2)>>> divmod(1+2j,1+0.5j)((1+0j), 1.5j)

PS: Python standard library: built-in function divmod (a, B)

This function implements dividing a by B and then returns the tuples between the operator and the remainder. If both parameters a and B are integers, integer division is adopted, and the result is equivalent to (a // B, a % B ). If a or B is a floating point number, it is equivalent to (math. floor (a/B), a % B ).

Example:

#divmod() print('divmod(2, 4):', divmod(2, 4)) print('divmod(28, 4):', divmod(28, 4)) print('divmod(27, 4):', divmod(27, 4)) print('divmod(25.6, 4):', divmod(25.6, 4)) print('divmod(2, 0.3):', divmod(2, 0.3)) 

The output result is as follows:

divmod(2, 4): (0, 2)divmod(28, 4): (7, 0)divmod(27, 4): (6, 3)divmod(25.6, 4): (6.0, 1.6000000000000014)divmod(2, 0.3): (6.0, 0.20000000000000007)
