Re: Random Number Generator

Leif,

1)  What is z.digit(6)?  I saw nothing for a parameter.  Or was
compute z = x * x
supposed to be
comput z = x * y

compute x = 12345 + hh * 3600 + ss * 60 + mm
is the same as
x = 12345 + (hh * 3600) + (ss * 60) + mm
lowest possible value would then be
01:01:01
x = 12345 + (01 * 3600) + (01 * 60) + 01
or 16006
then 16006 * 16006 = 256,192,036
highest possible value would then be
23:59:59
x = 12345 + (23 * 3600) + (59 * 60) + 59
or 98744
then 98744 * 98744 = 9,750,377,536

Basically though, time of day is not really generally accepted practice.
Frankly not enough randomness, and it tends to be stacked at time of most
use.

get time of day hh:mm:ss
compute x = 12345 + hh * 3600 + ss * 60 + mm
compute z = x * x

this gives a ten-digit number z.
pin(1) = z.digit(6)
pin(2) = z.digit(4)
pin(3) = z.digit(5)
pin(4) = z.digit(7)
