String to Float64: multiple-value strconv.ParseFloat() in single-value context

Question

I have an array of STRING slices like this:

[[header1 header2 startdate enddate header3 header4] 
[item1 100 01/01/2017 02/01/2017 5343340.56343 3.77252223956]          


        

Answer 1

The error you are getting is because the function ParseFloat returns two arguments and you are ignoring the second.

j, err := strconv.ParseFloat(i[4], 64)
if err != nil {
  // insert error handling here
}
(...)

Try to always check the function's signature in godocs before using it.
