Hello,
I'm trying to generate 30 random integer numbers between 0 and
1,000,000 but I keep getting negative values. This is my IDL
statements:

FOR i = 0, 29 DO BEGIN

weights[i] = ULONG(1000000 * RANDOMU( seed, 1 ))

ENDFOR

the result when I print out the array weights:

17925 28066 15706 -4558 7450 9892 5340 -1674 -29667
-15997
-27046 -27854 -24859 29529 -31310 -7807 21139 8014 -14189
-24471
-16476 -6624 -23456 3042 30319 -20737 10945 -19432 3206
-11725

I would think if you cast ULONG onto the calculation, you would get
postitive values.
thanks in advance.
