sum

str.sum(n=16) â integer

Instance Public methods

Returns a basic n-bit checksum of the characters in str, where n is the optional Fixnum parameter, defaulting to 16. The result is simply the sum of the binary value of each character in str modulo 2**n - 1. This is not a particularly good checksum.
