视频打印次数求教

救赎自我-

>>> i = 0
>>> while i < 1:
        i = i+0.1
        print("Cl is my baby!")

       
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!
Cl is my baby!

请问为什么是打印11次呢 而我换成整数就是10次

>>> i = 0
>>> while i < 10:
        i = i+1
        print(i)

       
1
2
3
4
5
6
7
8
9
10

浮点数运算有误差的，第十次是0.9999999，也当小于1了

1. >>> i = 0
   
2. >>> while i < 1:
   
3.         i = i+0.1
   
4.         print("Cl is my baby!",i)
   
5. 
   
6.        
   
7. Cl is my baby! 0.1
   
8. Cl is my baby! 0.2
   
9. Cl is my baby! 0.30000000000000004
   
10. Cl is my baby! 0.4
    
11. Cl is my baby! 0.5
    
12. Cl is my baby! 0.6
    
13. Cl is my baby! 0.7
    
14. Cl is my baby! 0.7999999999999999
    
15. Cl is my baby! 0.8999999999999999
    
16. Cl is my baby! 0.9999999999999999
    
17. Cl is my baby! 1.0999999999999999

1. i = 0
   
2. while i < 1:
   
3.     i = round(i+0.1, 1) # 使用 round() 函数减少浮点精度误差
   
4.     print("Cl is my baby!")
