Yes that's a real website.

maxobjects.com will bring up some externals which can
output pi - if you need it more accurate than possible
with 32 bit (which i doubt for expr.)

then you can use a variable (f$1) in your expr and feed
it the number.

I'm not sure what you're doing with expr, but it's probably a lot easier to use the js object for this. That way you can access the Javascript constant Math.PI in your expression.

This is only true if you are as fluid in javascript as in Max -
wait, its obviously not true:
Math.PI will eat up 7 characters, 3.141593 will eat 8, but as you need
some other lines of code in js, you need a lot more characters. If you
use my "pi" abhaXion, you need only 2 plus one patch chord... ;-)

save as pi:

expr's interface to the outside world is 32-bit floats (and integers). So 3.141593 is as close as you're gonna get anyway.

For that you need a symbolic constant?

[expr 22. / 7.] should be good enough for anybody.

Actually, [expr 355. / 113.] looks to be as close as makes no odds in
the 32-bit world.

thanks for all your replies.

i'm not into the js object, yet..
i'll just use the value inside expr. though it would be easier if there existed a symbol for it. like "p" for instance. maybe there's a good reason for not using this?

also:

[expr acos (-1.)]

but still puts out only 3.141593

so just ignore me :)
