Because the project needs to convert the 10-digit ID into a 62-digit string and share it with others. Therefore, I searched many algorithms on the Internet, but none of them met the requirements. The ID in the project is calculated by a fixed algorithm ~ The ulong integer of 20-bit data. For example, 17223162272256398107,509488277152981097. The algorithm found on the internet is that it is inaccurate to convert the ulong value to the ulong value afte
