If you need to round the data in your array to integers, then NumPy offers several options: numpy.ceil() numpy.floor() numpy.trunc() numpy.rint() The np.ceil() function rounds every value in the array to the nearest integer greater than or equal to the original value: Python >>> ...
astype会生成一个新的数组,而不会改变原始数组。 方法二:使用np.floor,np.ceil,np.round 有时候我们在进行转换时,不仅仅是简单地将小数部分去掉,而是希望通过向下取整、向上取整或四舍五入的方式来处理这些数据。 向下取整 # 向下取整array_floor=np.floor(array_float).astype(int)print("向下取整后的数组:",...

描述: 返回一个新的 bytes 数组。 bytearray 类是一个可变序列,包含范围为 0 <= x < 256 的整数。参数:如果是一个 string,您必须提供 encoding 参数(errors 参数仍是可选的);bytearray() 会使用 str.encode() 方法来将 string 转变成 bytes。如果是一个 integer,会初始化大小为该数字的数组,并使用 ...
Convert a number or string to an integer,orreturn0ifno arguments are given.If x is a number,returnx.__int__().For floating point numbers,thistruncates towards zero.If x is not a number orifbase is given,then x must be a string,bytes,or bytearray instance representing an integer lite...
①指定创建的数组的数据类型a=np.array([1,0,1,0],dpyte=np.bool)#dtype=’?’ ②修改数组的数据类型a.astype(“i1”)#a.astype(np.int8) ③numpy中的小数 t7=np.array([random.random() for i in range(10)]) t8=np.round(t7,2) ④同样,每种数据类型均有对应的类型转换函数,如float(32...
To round arrays in Python we have used the numpy module. Then this array is passed as an argument to the round() function with 4 decimal points to be rounded.Open Compiler import numpy as np # the arrray array = [7.43458934, -8.2347985, 0.35658789, -4.557778, 6.86712, -9.213698] res ...

str、byte、bytearray 只包含可打包对象的集合,包括 tuple、list、set 和 dict 定义在模块顶层的函数(使用def定义,[lambda]()函数则不可以) 定义在模块顶层的内置函数 定义在模块顶层的类 某些类实例,这些类的dict属性值或 [__getstate__()]()函数的返回值可以被打包(详情参阅打包类实例这一段) ...
