I have a sympy Float constant, e.g,
我有一个同情的浮动常数，例如，
x=Float(3.2)
I need to transform the floats to integers, i.e,
我需要将浮点数转换为整数，即
x+Int(3)
Is there any built-in method in sympy that can transform Float(3.2) to Int(3)?
在sympy中是否有任何可以将Float（3.2）转换为Int（3）的内置方法？

Casting a floating-point number to a SymPy integer:
将浮点数转换为SymPy整数：
In [1]: a = 3.2
In [2]: b = Integer(a)
In [3]: b
Out[3]: 3
SymPy integers behave mathematically under division:
SymPy整数在划分下以数学方式表现：
In [4]: b/2
Out[4]: 3/2
Casting the same floating-point number to a Python integer:
将相同的浮点数转换为Python整数：
In [5]: c = int(a)
In [6]: c
Out[6]: 3
In Python 3 or using future division, you can get back a floating point:
在Python 3中或使用将来的除法，您可以获得一个浮点：
In [7]: c/2
Out[7]: 1.5

Just use the Integer() method. It allows to convert the float to int. Integer() always brings the float down to a round figure.
只需使用Integer（）方法。它允许将float转换为int。 Integer（）总是将浮点数降低到圆形数字。

>>> a = 3.2
>>> b = Integer(a)
>>> b
