Author: gavin Date: Tue Feb 2 19:28:01 2010 New Revision: 203393 URL: http://svn.freebsd.org/changeset/base/203393 Log: The multiplicand a = 0x5deece66d = 25214903917, not 0xfdeece66d. This bug in the man page has gone unnoticed for over 15 years!

The modulo is always fixed at m = 2 ** 48. r(n) is called the seed of the random number generator.
