One such calculation is ceiling division, or the ceiling of the number you get after dividing two numbers. 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 functi...
()function. This function returns the ceiling value of the passed number. For example, if we pass2.3to this function, it will return3. We will pass the result of normal division to this function and return its ceil value. Refer to the following code for some more examples and their ...
| Ceiling of an Integral returns itself. dir(object)也很有用,它列出了对象可用的方法: >>>dir(float) ['__abs__','__add__','__and__','__bool__','__ceil__','__class__','__delattr__','__dir__','__divmod__','__doc__','__eq__','__float__','__floor__','_...
Calculates a number’s ceiling – the smallest following integer. Pass any decimal number to ceil() to get the next larger integer. What is the ceil() function in Python? The ceil() function in Python is used to calculate the ceiling value of a number. In Python, the ceil function is ...
3)ROUND_CEILING:如果Decimal为正,则做ROUND_UP操作;如果Decimal为负,则做ROUND_DOWN操作; 4)ROUND_FLOOR:如果Decimal为负,则做ROUND_UP操作;如果Decimal为正,则做ROUND_DOWN操作; 5)ROUND_HALF_DOWN:如果舍弃部分>.5,则做ROUND_UP操作;否则,做ROUND_DOWN操作; ...

可以用getcontext()函数得到当前运算环境的参数,直接打印 print (get context()),以我的为例子 Context(prec=28, rounding=ROUND_HALF_EVEN, Emin=-999999999, Emax=999999999, capitals=1, clamp=0, flags=[], traps=[InvalidOperation, Overflow, DivisionByZero]) ...
通常使用小数的开始是导入模块,使用 getcontext() 查看当前上下文,并在必要时为精度、舍入或启用的陷阱设置新值: >>> >>> from decimal import * >>> getcontext() Context(prec=28, rounding=ROUND_HALF_EVEN, Emin=-999999, Emax=999999, capitals=1, clamp=0, flags=[], traps=[Overflow, DivisionBy...
decimal.ROUND_CEILING 舍入方向Infinity。 decimal.ROUND_DOWN 舍入方向为零。 decimal.ROUND_FLOOR 舍入方向为-Infinity。 decimal.ROUND_HALF_DOWN 舍入到最接近的数,同样接近则舍入方向为零。 decimal.ROUND_HALF_EVEN 舍入到最接近的数,同样接近则舍入到最接近的偶数。
