// UpperCase is used with hexadeca.EncodeByte() to encode a byte into hexadecimal symbols using upper-case symbols from ASCII / Unicode UTF-8.
|

|
|
// I.e.,
|
|||
|
|
//
|
|||
|
|
// '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'
|
|||
|
|
//
|
|||
|
|
// Example usage:
|
|||
|
|
//
|
|||
|
|
// mostSignificiant, leastSignificant := hexadeca.EncodeByte(value, bytesymbols.UpperCase)
|
|||
|
|
//
|
|||
|
|
// If ‘value’ was 254 (== 0xFE) then ‘mostSignificiant’ would be 'f' and and ‘leastSignificant’ would be 'e'.
