Without precision, it rounds to nearest integer. Note the bankers rounding for 0.5 cases. With precision argument, it rounds to specified decimal places. The function returns a float even when rounding to whole numbers with precision specified. ...
6、考虑使用decimal模块:如果你需要更精确的控制或更可靠的舍入行为,可以考虑使用Python的decimal模块,这个模块提供了Decimal类,用于高精度的十进制数运算和舍入。 7、了解Python版本之间的差异:不同版本的Python可能对round()函数的行为有所不同,特别是Python 2和Python 3在舍入到偶数的方式上有所不同,确保你了解...

Python uses the math module, NumPy, and Pandas libraries to offer different methods of rounding up numbers. Round up using the math module The math.ceil() function from math is used to round up a number to the nearest integer. The syntax is shown below. # Import the math module to acce...
To round every value down to the nearest integer, use np.floor(): Python >>> np.floor(data) array([[-1., -3., -1., 0.], [ 0., 0., -1., 0.], [-1., -1., 0., -1.]]) You can also truncate each value to its integer component with np.trunc(): Python >>>...
