J42 Random Number Generator -

This application will generate a sequence of 2, 3 or 4 digit numbers that cannot be reasonably predicted. Tap a digit to turn it off or on. Any noticeable predictability is nothing more than a random chance or coincidence. No individual digit can be predicted from knowledge of any other digit or group of digits.

The minimum output value is "0000" and the maximum output value is "9999". Optionally, the minimum value can be be increased to "1000" by a program setting. The random set can be further reduced by a program setting which will eliminating duplicate digits in the result. Even further reduction in the output set can be obtained by reducing system entropy through a program setting.

The RNG (random number generator) 'seed' is based on the current time in nanoseconds. This is a rapidly changing value and controls whether the random number generator produces a new set of random numbers or repeats a particular set of random numbers. This assures no two invocations of the program will produce the exact same sequence of result numbers. The seed can be manually set through a program setting. Manually setting the seed will cause the program to repeat the exact same number sequence. Useful to amaze your friends at your ability predict numbers.

System entropy can be reduced by a program setting. Using this setting will severely impact the result set and a min/max of 10 numbers will be generated. As entropy is reduced with each generated number, predictability greatly increases and is no longer a matter of random chance or coincidence.

The use of the application is strictly for your personal entertainment. Other versions of this application produce varying results sets. This version produces 1,2,3 or 4 digit results.
