1、浮点数的精度问题:由于计算机内部表示浮点数的方式,有时候round()函数的结果可能不是完全符合预期,这通常发生在需要高精度的金融计算或科学计算中。例如,round(2.675, 2)在某些情况下可能返回`2.67`而不是`2.68`。 2、四舍五入规则:round()函数使用标准的四舍五入规则,即如果小数点后的第三位是5或更大,则...
You can use round() to round a number to the nearest integer:Python >>> round(2.3) 2 >>> round(2.7) 3 round() has some unexpected behavior when the number ends in .5:Python >>> round(2.5) 2 >>> round(3.5) 4 2.5 is rounded down to 2, and 3.5 is rounded up to 4. ...

print(round(3.5)) # Output: 4 # NumPy rounds to nearest even integer (also banker's rounding) print(np.round(2.5)) # Output: 2.0 print(np.round(3.5)) # Output: 4.0 # But NumPy works on entire arrays at once numbers = np.array([1.5, 2.5, 3.5, 4.5]) ...
6. Round to Nearest Even (Bankers' Rounding) Write a Python program to configure rounding to round to the nearest integer, with ties going to the nearest even integer. Use decimal.ROUND_HALF_EVEN Click me to see the sample solution

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...
and almost all platforms map Python floats to IEEE 754 binary64 “double precision” values. IEEE 754 binary64 values contain 53 bits of precision, so on input the computer strives to convert 0.1 to the closest fraction it can of the formJ/2**NwhereJis an integer containing exactly 53 bit...
