I am trying to print a
string with a
uint64 but no combination of
strconv methods that I use is working.
log.Println("The amount is: " + strconv.Itoa((charge.Amount)))
cannot use charge.Amount (type uint64) as type int in argument to strconv.Itoa
How can I print this
strconv.Itoa() expects a value of type
int, so you have to give it that:
log.Println("The amount is: " + strconv.Itoa(int(charge.Amount)))
But know that this may lose precision if
int is 32-bit (while
uint64 is 64), also sign-ness is different.
strconv.FormatUint() would be better as that expects a value of type
log.Println("The amount is: " + strconv.FormatUint(charge.Amount, 10))
For more options, see this answer: Golang: format a string without printing?
If your purpose is to just print the value, you don’t need to convert it, neither to
int nor to
string, use one of these:
log.Println("The amount is:", charge.Amount) log.Printf("The amount is: %d\n", charge.Amount)
