Functions

func ExpandAndSeparateCurrencyString

func ExpandAndSeparateCurrencyString(input string) string

ExpandAndSeparateCurrencyString expands the input string, then applies comma separators

func ExpandCurrencyString

func ExpandCurrencyString(input string) string

ExpandCurrencyString takes a string with a token suffix and expands it with the appropriate number of zeroes. The input string may contain a decimal point, and it will expand it, standard form style. By conventtion hex balances have a leading 0x, decimals are bare. THis function will work correctly with either. This function returns Attoms.

func FormatCurrencyString

func FormatCurrencyString(input string) string

FormatCurrencyString ...

func FormatTokenString

func FormatTokenString(input string) string

FormatTokenString is a wrapper to FormatUnitString

func FormatUnitString

func FormatUnitString(input string, power int) string

FormatUnitString takes an atomic input and returns
