Phi is about 1.61803.....  (see previous post)

Interesting values in the following formula;  A^2-A

A=1;  A^2 - A = 0.0000....

A=1.60;   A^2 - A = 0.9600

A=Phi;  A^2 - A = 1.0000....

A=1.62;  A^2 - A = 1.0044

A=2;  A^2 - A = 2.0000....


For all other number besides Phi, with this formula, will equal something other than 1.00000....

Also interesting;

A=Phi; A - (1/A) = 1.0000....

Phi in terms of  "1";

Phi = (1+sqrt(1+1+1+1+1)) / (1+1)
