Python: Remove division decimal
提问by Arctoran
I have made a program that divides numbers and then returns the number, But the thing is that when it returns the number it has a decimal like this:
我制作了一个程序，将数字相除，然后返回数字，但问题是当它返回数字时，它有一个像这样的小数：
2.0
But I want it to give me:
但我希望它给我：
2
so is there anyway I can do this?
所以无论如何我可以做到这一点吗？
Thanks in Advance!
提前致谢！

You can call int()on the end result:
您可以调用int()最终结果：
>>> int(2.0)
2

When a number as a decimal it is usually a floatin Python.
当一个数字作为小数时，它通常是floatPython 中的 a。
If you want to remove the decimal and keep it an integer (int). You can call the int()method on it like so...
如果要删除小数并保留整数 ( int)。你可以int()像这样调用它的方法......
>>> int(2.0)
2
However, introunds downso...
然而，int几轮下来所以......
>>> int(2.9)
2
If you want to round to the nearest integer you can use round:
如果你想四舍五入到最接近的整数，你可以使用round：
>>> round(2.9)
3.0
>>> round(2.4)
2.0
And then call int()on that:
然后调用int()它：
>>> int(round(2.9))
3
>>> int(round(2.4))
2

>>> int(2.0)
You will get the answer as 2
你会得到答案为 2
回答by Himanshu
You could probably do like below
你可能会像下面这样
# p and q are the numbers to be divided
if p//q==p/q:
print(p//q)
else:
print(p/q)

def division(a, b):
return a / b if a % b else a // b

There is a math function modf()that will break this up as well.
有一个数学函数modf()也可以分解它。
import math
print("math.modf(3.14159) : ", math.modf(3.14159))
will output a tuple:
math.modf(3.14159) : (0.14159, 3.0)
将输出一个元组：
math.modf(3.14159) : (0.14159, 3.0)
This is useful if you want to keep both the whole part and decimal for reference like:
如果您想同时保留整个部分和小数以供参考，这很有用，例如：
decimal, whole = math.modf(3.14159)
decimal, whole = math.modf(3.14159)
