Is it possible to write a pi program in turing, that will determine the value of pi to infinte decimals.... always wondered...

not infinite... turing has limits, very small limits, and it'll crash at a couple of decimal places... but you can find pi using turing using the trig functions.. i think

Confused

Anyways, you can calculate pi using the chaos theory. I dont remember it exactly, but it involved the addition of random numbers. You might be surpriced, but thats actually how pi is calculated Laughing

code:
put 4*(arctan (1)) : 1: 48


Wonder what will happen if i export it to a file.. hmmm

Ha.. the max output for a number is 50 digits in turing.. hardly enough

not much.

you're trying to assign a real value to an integer, so turing isn't going to do anything but give you an error telling you so. and even if it did (ie, you change the int to a real), the result only has 6 decimal places (3.141593)
