(algorithm)
Definition: A hash function that uses the first p bits of the key times an irrational number.
Formal Definition: h(k) = 
m(k A (mod 1))
, where m is usually an integer 2p and A is an irrational number (or an approximation thereto) 0 < A < 1. The modulo 1 operation removes the integer part of k × A.
