Python引入了按目录来组织模块,称为包,Package,比如: extensions ├─ __init__.py ├─ dog.py └─ cat.py 现在dog.py模块的名字就变成了extensions.dog, 请注意,每一个package目录下面都会有一个__init__.py 的文件,这个文件是必须有的,否则,Python就把这个目录当成普通目录,而不是一个package directory。
1、python中fromfutureimport division python2.7版本中整数相除得出的结果不显示小数,调用fromfutureimport division后则可显示小数 示例: a =9/2print(a)#输出:4调用from__future__importdivision后#输4.5 2、fromfutureimport print_function 在代码开头加上fromfutureimport print_function这句之后,即使在python2.X...
In the Python language, we have the // -- > operator for floor division, but there is not a built in function which performs ceiling division. However, we can create our own function to do ceiling division utilizing the mathematical fact that negative one times the floor of a negative num...
“floor 函数”也被称为“最大整数函数”(greatest integer)或“整数函数”(entier function),该函数获得的值是一个变量“x”的整数部分。 整除or 地板除,一词两译哪个才是正确的? “取整除”也是很对的,“取整除”运算取的就是除法结果的整数部分。 在中文中,“除法结果”有一个专门的术语,叫“商”。 关...

Currently used division has good speed -- in fact, we just make 1 division (expensive) and multiplication (not so expensive), but precision is poor. I suggest adding separate function (smth like preciseDecimalDiv(a: Decimal, b: Decimal, prcsn: UInt8) with user-defined result precision) fo...
