cost_per_friend = float(meal_cost) / float(friends) We have converted both “meal_cost” and “friends” to a floating point number. This is because the input() method returns a string. You cannot perform a mathematical calculation on a string value using Python’s math operators. Now, ...
To round all of the values in the data array, you can pass data as the argument to the np.round() function. You set the desired number of decimal places with the decimals keyword argument. The NumPy function uses the round half to even strategy, just like Python’s built-in round()...
round 函数的实例 下面就来给大家举一些 round 函数的实例,帮助大家快速掌握它 的用法: 例 1: #!/usr/bin/python3 a = 3.1415 #Round off to 2 decimal places print(Round off to 2 decimal places : round(a,2)) #Round off to nearest integer print(Round off to nearest integer : round(a)) ...
round(10):rounds the integer to10 round(10.7):rounds the float10.7to nearest integer,11. round(5.5):rounds the float5.5to6. Example 2: Round a number to the given number of decimal places print(round(2.665,2))print(round(2.675,2)) Run Code Output 2.67 2.67 When the decimal2.675is con...

[[1. 3. 4.] [4. 6. 6.]] In this example, thenp.round()function rounds the elements of the array to the nearest integer. However, even after rounding, the data type of the array remains asfloat64. That is the reason for the presence of a decimal point in the output. ...
python3官方文档也给出过解释 The behavior of round() for floats can be surprising: for example, round(2.675, 2) gives 2.67 instead of the expected 2.68. This is not a bug: it’s a result of the fact that most decimal fractions can’t be represented exactly as a float. See Floating ...
Python NumPyround()is a built-in function used to return the rounded values of the source array to the nearest integer. It also takes the decimal values to be rounded. If the decimal places to be rounded are specified then it returns an array that contains a float number that will be ro...
