go - How to convert hex to float

Question

I have to convert hex, represeneted as strings (e.g. "0xC40C5253") to float values (IEEE-754 conversion). I did not manage to do that using the strconv.ParseFloat function. Is there anything else I have to use? I couldn't find it so far. I also tried converting it to an integer first and then to a float, but the results were wrong.

Code of my last try:

package main

import (
  "fmt"
  "strconv"
)

func main () {
  x, err := strconv.ParseInt("C40C5253", 16, 64) 
  f, err := strconv.ParseFloat(fmt.Sprintf("%d", x), 64) 

  if err != nil {
    fmt.Printf("Error in conversion: %s
", err)
  } else {
    fmt.Println(f)
  }
}
