When I set a float variable to 3.1, why is printf printing it as 3.0999999? []

How can I print a '%' character with printf? []

How can printf use %f for type double, if scanf requires %lf? []

Why doesn't the code "double d; scanf("%f", &d);" work? []

How can %f be used for both float and double arguments in printf? []
