llBase64ToInteger

Function: integer llBase64ToInteger( string str );

Returns an integer that is str Base64 decoded as a big endian integer.

Base64 string

Caveats

If str contains fewer than 6 characters, any incomplete least-significant bytes of the integer are set to 0.
- For example, the Base64 value "qqqqqq==" corresponds to the hexadecimal value 0xAAAAAAAA. If the padding "=" characters and the last "q" are dropped, there are 5*6=30 bits remaining and those can form only 3 full bytes (24 bits). The result is 0xAAAAAA00.
- The Base64 value "qqqq" has 4*6=24 bits available, which is enough for the same 3 full bytes. The result is also 0xAAAAAA00.
- Similarly, 3-character Base64 has 18 bits, enough for 2 bytes, and 2-character Base64 has 12 bits, enough for one byte.
- Finally, single-character Base64 has only 6 bits and thus no complete bytes, and the result is always zero.
Returns zero if str is longer than 8 characters.
