The error message "is not a valid floating point value" typically occurs when trying to convert a string to a floating point number, but the string is not properly formatted as a number. For example, if you try to convert the string "hello" to a float, you will get this error message because "hello" is not a valid number. Similarly, if you try to convert the string "1.2.3" to a float, you will get this error because it is not a properly formatted number. To fix this error, you need to ensure that the string you are trying to convert to a float is a valid number. You can use the `isnumeric()` or `isdigit()` methods to check if a string is a valid number before trying to convert it to a float.
