### Random number generation…

February 19, 2007 | 2:55 pm

I’m wondering how I can set the min/max values of a random object, on the fly via two hsliders? I am already using the minimum and maximum objects to determine the absolute min/max values of the two hsliders. Now I need to use the outputs of minimum and maximum to set the min/max values for the random object…

Thanks!

p.s. Sorry for so many posts, I have to build a patch for tomorrow…

I have now found a solution via the scale object…

Thanks!

I take you need to get a number between two values? If so, give this a
try… It’ll only work for integers. Floats are a little trickier.

The stock random has a fixed minimum of zero. Also note that one of
the most common errors in the world is to think that you are setting
the maximum value of random. You set the number of different integers
random can create, which run from 0 .. n-1.

If you want a random number generator with inlets for min and max,

You can patch to get random to do what you want, but lp.tata is an
industrial-strength random number generator. And if you want values
between -25 and 37 it does the thinking for you.

Best,
Peter
