C++: comparison precision

Who can explain this output? One less zero, and it's "false" #include <iostream> using namespace std; int main() { float a = 2.0000001; int b = 2; if(a == b){ cout << "true!"; } else { cout << "false"; } return 0; }

Is this true independently from the compiler?

Also, can you tell me if this code precision can be improved? https://code.sololearn.com/chgZD5KdzV9m/?ref=app
