randomn problem [message #52956]

Hi all,

I was playing around with randomn and noticed some weird behavior:

IDL> print, stddev(randomn(seed, 1e7))

I consistently get back numbers around ~0.992. I've tried it on a
different computer, and the result was not exactly the same, but
similar. If I change 1e7 to 1e8, the problem gets worse, and I get
~0.853. I've tried the syntax with floats, integers, and longs, and I
still get the same answer. Does anyone know what could be going on?
