The mathematical relation of a circle's diameter to its circumference is usually taken to be 3.14159... This value however is an irrational number and contains an error which is simple to see when one realizes a whole diameter exists within a whole circumference. The true value of

**PI**as given by Keely/Parker is 20612 : 6561 which must remain an integer ratio of two whole numbers and NEVER REDUCED to a decimal equivalent, which is where the error comes in. These numbers ought to be regarded as parts of a whole relative to each other. A straight line is not the same thing as a curved line so to divide one into the other is inconsistent.
