Hi all,

this morning I started writing some monte carlo code, in which I'm
generating random arrays, and scaling/shifting them to fit the (gaussian)
distribution parameters I need. One thing is not clear in the online help:
Which random function is "better"? Should I be using randomn() or
randomu()? The help is explicit about the algorithms used, but there is
comparison between the randomness of the two functions. And since both
functions accept a /normal flag, it's unclear as to which is the better
choice.

Is there any common wisdom that makes this choice obvious?

cheers
chris
