from decimal (ulong) to Base radix
inverse transformation
The possible practical use of the other radix may be the compact form of string representation of a number in names of graphic objects. For example, 64-bit number generally has the following number of chars:
decimal: 20 chars (ULONG_MAX)
hexadecimal: 16 chars
base 36: 11 chars
base 128: 10 chars
the optimal is the base 36 radix.
