Here you can find the source of longToBaseCode(char[] target, int targetOffset, long value, int base, int lengthLimit, boolean fillZeros, boolean upperCase)
| Parameter | Description |
|---|---|
| target | target characters array |
| targetOffset | offset position in target array |
| value | value |
| base | target numerical base, supported values are 1 to 16 |
| lengthLimit | length limit |
| fillZeros | flag if rest of the value should be filled with zeros |
| upperCase | upper case for values greater than 9 |
