That's a Marine size pi, Phil, but if you wish, I'm sure Terry can cut you a slice of civilian size pi.

@Terry:
Just noticed, in lesson 2, in your CONSTANTS explanation, line 13, you give the circumference of a circle as R*(pi squared), instead of R*pi*2. (As you know,  R*(pi squared) is the area).

Not quite, area is Pi * r ^ 2 ( not Pi  ^ 2 ) and yes, circumference is  2 * Pi * r.

Speaking of Pi there is a QB64 Function _Pi(x) that will return multiples of Pi eg, _Pi(2) is circumference of a unit circle, a circle with radius = 1.

@bplus: Yes, sorry, got a bit excited there, and made a similar mistake! But I think it still needs to be corrected.
And I didn't know about the _Pi(x) function; thanks.

[bplus]

Yes either correct the formula for circumference or the application for Area of Circle

Yeah I am still learning all the new _NonQB4.5 compatibles.

I'm still trying to stop the _NonNew functions from disappearing into the dim regions of my brain!

I don't like "$NOPREFIX" because it could cause confusion about which keyword was created by Dartmouth or by M$, and which was not. And Freebasic having something that allows "new" keywords used in program which are supposed to be edited away from Q(uick)Basic but I guess some people want to go back to 16-bit, like the ones using music tracker software...

EDIT: Good job with the warning near the top of the lession #5.

Oh son of a pup.  That was on my "to fix" list from the previous tutorial as well. Argh. Fixing it now.

Edit: all fixed. Wow, so much easier to edit with Google Sites.

Semper Pi !

Please, we're all trying to recover from the last pundemic in a different thread.
