python每日一函数 - divmod数字处理函数

divmod(a,b)函数

中文阐明:

divmod(a,b)办法回来的是a//b(除法取整)以及a对b的余数

回来成果类型为tuple

参数:

a,b可认为数字(包含复数)

版别:

在python2.3版别之前不允许处理复数,这个咱们要注意一下


英文阐明:

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代码实例:

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