|return_text=that is '''str''' {{LSLGC|Base64}} decoded as a big endian integer.
|spec
|caveats=*If {{LSLPT|str}} contains fewer than 6 characters, any incomplete least-significant bytes of the integer are set to 0.
**For example, the Base64 value <code>"qqqqqq=="</code> corresponds to the hexadecimal value <code>0xAAAAAAAA</code>. 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 <code>0xAAAAAA00</code>.
**The Base64 value <code>"qqqq"</code> has 4*6=24 bits available, which is enough for the same 3 full bytes. The result is also <code>0xAAAAAA00</code>.
**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 {{LSLPT|str}} is longer than 8 characters.
