im assuming you are trying to convert the string into an integer and a float. In this case the reason its not correct is that you are performing your to_i and to_f methods on "integer" and "float" which have no values assigned to them and trying to assign the result to the variable "string"

integer = string.to_i
float = string.to_f

this will perform the methods on the string variable and save the result to new variables called integer and float
