Radix-16 Powers of Ten less than 255 * ln(65536) / ln(10)

C# .NET ToString() hexadecimal conversion for a ulong type only delivers the low 16 hex digits of any numeric value. So if you're trying to break the 64-bit barrier for string conversions to base 16 or base 10, you can use the values from the table (for powers of ten less than 10¹²²⁸) at this link as benchmarks or in constructing a table-driven binary-to-decimal string converter:

If you don't modify the file, you can read it as straight binary in this format.

Here's a quicker download (281K for the .zip file as apposed to 1.2M for the uncompressed .txt file):
