How to make random numbers?

[Mark Fulford]

I want three random numbers from my script in the range 0 to 50000 that are different each time the script is run on the same PC.

I am generating the number as follows:
RANDOM1 = Generate Random Number (max value 50000)
RANDOM2 = Generate Random Number (max value 50000)
RANDOM3 = Generate Random Number (max value 50000)

These are sample results:
RANDOM1 = 2400
RANDOM2 = 700
RANDOM3 = 1300

RANDOM1 = 4300
RANDOM2 = 2700
RANDOM3 = 4700

RANDOM1 = 1400
RANDOM2 = 2900
RANDOM3 = 3500

Clearly I've got something wrong, but what?

And what is the actual result?

[MichaelNesmith]

I believe the max of this function is 32767, in case that is what's bothering you with the results.

[Gizm0]

Yes, the MAX_INT value on Windows is 32767..If you want more, you have to multiply it, or create a custom dll and get the result from there!

The help file does not give sufficient detail of functions such as this. For example, what are the purposes of the two seed parameters?

[MichaelNesmith]

They seed the random number generator with the specified number. Each seed must be unique for the random number generation to be truly pseudo-random. Please see the Serial Validation example project for detailed real-world usage of these functions.

What I'm getting at is that the Help file is a bit light. For each function it should include information about parameters and results, such as the limit to the size of a random number and the range for seeds. A worked example within the Help file would also be quite normal.
