javascript - In the for loop, why is the s output by the expression s+=0.01 not an arithmetic sequence?

Question

Logically speaking, the output should be
0.01
0.02
0.03
0.04
0.05
0.06
0.07
0.08
0.09
1.00
1.01
Why is the output result like the picture above? Why do so many decimals suddenly appear?
