To convert a string with scientific notation to float64 using strconv in Go, you can use the ParseFloat function from the strconv package. Here's an example:
package main
import (
"fmt"
"strconv"
)
func main() {
scientificNotation := "1.23e+6"
converted, err := strconv.ParseFloat(scientificNotation, 64)
if err != nil {
fmt.Println("Error:", err)
return
}
fmt.Println(converted)
}
In this example, we have a string scientificNotation which contains the scientific notation representation of a number (1.23e+6). We use strconv.ParseFloat to convert this string to float64. The second argument 64 in ParseFloat represents the bit size of the resulting float. In this case, 64 is used for float64.
If the conversion is successful, converted will hold the converted value. Otherwise, an error will be returned. In case of an error, the error message will be printed.
Running this code will output:
1230000
which confirms the successful conversion of the scientific notation to float64.
