# Pi and A= 3,141 592 653 589 793 ... ... ...10

Hi

A = 3,141 592 653 589 793 ... ... 10 (note that the triplets are always different from 10.)

A = U0 + U1 + U2 + U3 + U5 ...Un

with U0 = 3, U1 = 0.141 U2 = 0.000592 ... Un = 0.000000 ....... 10.

Pi tends to a decimal number A when n goes to infinity?

Are you trying to suggest something useful?

Do you mean Pi IS the decimal number 'A', like 1 = 0.9999...?

yes when n tends to infinity pi = A and A is a decimal number so pi is also a decimal.

As you add more decimal places, you get closer. Yup. Doesn't suggest anything, but I'll give you a nice "yup".

What does it mean in your mind for a number to be "a decimal"? It can be expressed in decimal notation, yes (without terminating or repeating); but that's true of any number.

And what is the point of the "10" at the end of each approximation A?

u0 u1 u2 ... are a number between 0 and 999 different from 10.
that's why when n tends to infinity Un = 10

It is incorrect to say that "pi tends to a decimal number". pi is a decimal number. Other than that I don't understand what you are trying to say.

I too feel (actually know) that pi is a decimal number.
These triples you speak of go on forever so what is this 10 all about.
Also I doubt that no triple in pi is 010.

either a segment 1 equal to Pi = 3.414 ..
and a segment 2 equal to U = 10 ^ -n for all
n ~ infinite.
A=segment 1+segment 2=Pi+10^-n for all n~infinite.

Exemple Xn+a=X for all n~infinite ans a#0.
Limite Xn+a= limite X.

Limite A=limite pi+limite 10^-n
A=pi
A is decimal is pi decimal.

Forgiveness is (X ^ n) + a = X
