Question

https://code.sololearn.com/cNKy8KGbEylr/?ref=app

Shouldn't it do it 4 times since a=100 and it is supposed to be executed when a<100?

Answer 1

Be cause
0.01 < 100
10*0.01 = 0.1 < 100
10*0.1 = 1 < 100
10*1=10<100
and 10*10 =100 but the incrementation is do after

Answer 2

0.01 ,i=1
0.10,i=2
1,i=3
10,i=4
100 but it's equal to a ,so it should be 4 as you said🤔

float has less precision
use double ,
