**VEX NOOB** create random float values

Hi there !

I just started to do some little things in vex!

I can't understand  how to create a random integer attribute.

 

If i put down an attribute wrangle on some points and I type in:

 

f@number = rand(@numpt);

 

I can get some random float values.

 

But if i write in :

 

i@number = rand(@numpt);

 

I can just get 0 on all my points.

 

I think is very simple but I cannot sort it out! may be with a fit function?

 

thanks!

By default rand function creates a random number between 0 and 1 from a seed.

Multiply this value

i@rand_num = int(rand(@ptnum)*10);

or use fit function

i@rand_num = int(fit(rand(@ptnum), 0, 1, 0, 10));

And also in your example you used a @numpt as seed (which is return total number of points). 

Hope it's help.
