UiTokenAmount data type

[lucasoares]

What is the reason the UiAmount *float64 is deprecated? I saw the blame information and apparently, the UiAmount was previously of the type *bin.JSONFloat64.

I don't know which field is reliable and when I should use each one of them... And if I use the string type, should I use a type from bin library to parse it?

let's refer to the documentation of solana RPC.

• amount: <string> - the raw balance without decimals, a string representation of u64
• decimals: <u8> - number of base 10 digits to the right of the decimal place
• uiAmount: <number|null> - the balance, using mint-prescribed decimals DEPRECATED
• uiAmountString: <string> - the balance as a string, using mint-prescribed decimals

I'd recommend parsing amount and using decimals for your internal calculations

to achieve this bin is not mandatory. Just use stdlib

// to uint64
amnt, err := strconv.ParseUint(amount, 10, 64)

// or to *big.Int
amnt, ok := new(big.Int).SetString(amount, 10)
