No tricks, but you can use the C format codes in IDL

f=randomn(seed, 10,10)
print, format='(10(%"%0.5f "))',f[0,*]

That will write out floating point numbers with 5 decimal places and a
single space between each number. Your emacs loving
friends will disown you for breaking their copy-rectangle-to-register,
but I think it's what you want.
