How to generate random binary number "16 bits" ?

[GerdW]

Hi Marina,

you use RandomNumber from numerics palette. Then you scale the number to your "16 bits" range as needed…

But it cannot be binary .. I changed it to be unsigned 16 bit inside a loop with constant counter = 15 to be looped 16 times but I got 4 bits I don't know why ! Any Idea ?

Hi Marina,

when you run a loop 16 times and only get 4 bits you definitely made something wrong.

It would help when you attach your VI…

here is the VI

If you are asking to have a random unsigned 16bit integer, this will do the trick

Bowen's example will have a slight bias towards zero in any give bit because when the random number is exactly 0.5, it will round down to zero instead of up to 1.  (random number range is 0 to .99999.....)

Awang's example is not very good either, actually worse, because it will have a bias away from 0 and 65535 happening about 1/2 as often as the other numbers because the way it rounds to nearest.

The proper implementation is to multiply by 65536, then round down.
