How to convert float to string
I read a float from a file and will have to convert it to string. My problem here is that I am unsure of how many digits will be there after the decimal. I need to take the float exactly and convert it to string.
For ex:
1.10 should be converted to "1.10"
Also,
1.5 should be converted to "1.5"
Can someone suggest how to go about this?
string go floating-point precision

Use strconv.FormatFloat like such:
s := strconv.FormatFloat(3.1415, 'E', -1, 64)
fmt.Println(s)
Outputs
3.1415

FormatFloat converts the floating-point number f to a string, according to the format fmt and precision prec. It rounds the result assuming that the original was obtained from a floating-point value of bitSize bits (32 for float32, 64 for float64).
func FormatFloat(f float64, fmt byte, prec, bitSize int) string
f := 3.14159265
s := strconv.FormatFloat(f, 'E', -1, 64)
fmt.Println(s)
Output is "3.14159265"
Another method is by using fmt.Sprintf
s := fmt.Sprintf("%f", 123.456)
fmt.Println(s)
Output is "123.456000"
