---------------------------------------------------------------------- hash (Lib) ---------------------------------------------------------------------- hash : int -> string -> int * int -> int SYNOPSIS Hash function for strings. KEYWORDS hash. DESCRIBE An invocation {hash i s (j,k)} takes an integer {i} and uses that to construct a function that, given a string {s}, will produce values approximately equally distributed among the numbers less than {i}. The argument {j} gives an index in the string to start from. The {k} argument is an accumulator, which is useful when hashing a collection of strings. FAILURE Never fails. EXAMPLE - hash 13 "ishkabibble" (0,0); > val it = 5 : int COMMENTS For better results, the {i} parameter should be a prime. This is probably not an industrial strength hash function. ----------------------------------------------------------------------
