Description:
ChecksumAdler32 ( text ; seed1 ; seed2 )
The initial values for seed1 and seed2 must be 1 and 0 respectively.
Adler-32 is a checksum algorithm which was invented by Mark Adler.
This custom function was written by Vaughan Bromfield <vbromfield@optusnet.com.au>.
This function is based on the algorithm published on the Adler-32 page on Wikipedia (accessed 2010-02-17)
http://en.wikipedia.org/wiki/Adler-32
The published algorithm used ASCII encoding and returns a hexadecimal result; this cf implementation uses Unicode encoding and returns a decimal (base 10) result.
There may be other differences.
All care taken but no responsibility. Your mileage may vary.
