In this code, dd (without quotes) is a variable that holds a value of 3.2. But "dd" (with quotes) is a String literal that has nothing to do with the variable or its value. So "dd" has no meaning as a float.

"3.2" (with quotes) is also a String literal, but it is in a format that can be parsed to a float.

If you want to assign the value of variable dd to your float, just assign it (with a cast to make sure it fits):
