Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I'm sure I used to know this but have forgotten. How would I generate a random number between say 1 and 70. The manual says....

Quote RND( number )
or
RND
Returns a pseudo-random number in the range of 0 to 0.999999. The
'number' value is ignored if supplied. The RANDOMIZE command reseeds
the random number generator.

I cant figure it out.

I use int((rnd*70)+1)

RND generates from 0 to up to but not including 1
x 70
+ 1 shifts it to 1 to 70
Int rounds them all down to the nearest integer
