Log:

The multiplicand a = 0x5deece66d = 25214903917, not 0xfdeece66d.
This bug in the man page has gone unnoticed for over 15 years!

particular formula employed is
r(n+1) = (a * r(n) + c) mod m
where the default values are
-for the multiplicand a = 0xfdeece66d = 25214903917 and
+for the multiplicand a = 0x5deece66d = 25214903917 and
the addend c = 0xb = 11.
The modulo is always fixed at m = 2 ** 48.
r(n) is called the seed of the random number generator.
