I want to 2 decimal points result for predicts on Python-CodePudding

My outputs have too much decimal points. But I want to 2 points float results. Can you help me?

EX: 42.44468745 -> 42.44

''' y_pred=ml.predict(x_test) print(y_pred) '''

Output: [42.44468745 18.38280575 7.75539511 19.05326276 11.87002186 26.89180941 18.97589775 22.01291508 9.08079557 6.72623692 21.81657224 22.51415263 24.46456776 13.75392096 21.57583275 25.73401908 30.95880457 11.38970094 7.28188274 21.98202474 17.24708345 38.7390475 12.68345506 11.2247757 5.32814356 10.41623796 7.30681434]

Since you didn't post all of your code, I can only give you a general answer.

There are three ways to get two decimals.

For example:

num = 1.223362719

print('{:.2f}'.format(num))

print('%.2f' % num)

print(round(num, 2))

You will get 1.22 as the result of any of these.

CodePudding user response：

Use round(num, round_decimal) For example:

num = 42.44468745

print(round(num, 2))

Output:

42.44
