First of all, I parsed the two values. I did this using the function ParseFloat, which is a member of the strconv or string conversion package. Notice that I'm using the TrimSpace function from the strings package to make sure that any extra space around the values is taken away. And then I'm also passing in a value of 64, meaning I'm getting back a float64, not a float32. Next, I check my error state. If the error isn't nil, that means there was an error.
