{I add - I actually like this a little better. Although I think a good
compiler would optimise them to be the same thing anyway)

Hello Justin!
Can you please send this to Java3D list for me. I get messages from the list
but have difficulties sending to it, since there are obviously problems at
my provider...
thanks,

Or without multiplication (in case you're doing it in a loop):
float my_float = (sign ? Random.nextFloat : -Random.nextFloat);
or
float my_float = Random.nextFloat;
my_float = (sign ? +myfloat : -myfloat);
