## What is the value of pi in base 12?

Duodecimal (base-12) pi: 3.18480 9493B 91866 4573A 6211B B1515 51A05 72929 0A780 9A492 74214 0A60A 55256 A0661 A0375 3A3AA 54805 64688 0181A 36830 . . . Tridecimal (base 13) pi: 3.1AC10 49052 A2C7 . . .

## What are the numbers in base 12?

The base-12 number system composed of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B. Such a system has been advocated by no less than Herbert Spencer, John Quincy Adams, and George Bernard Shaw (Gardner 1984). In fact, duodecimal still has its advocates, some of whom term it “dozenal.”

What is the value of φ?

1.61803
A quick description of the Golden Ratio: The Golden Ratio is often represented by Phi. Its approximate value it 1.61803… but more accurately is represented by (sqrt. of 5 + 1) / 2. As you notice Phi is an irrational number and has some very interesting properties and is often seen in the real world.

Is a clock base 12?

The numbers on this clock are a futuristic-looking numerical system called base-twelve. Base-twelve is exactly like how we normally count except instead of counting in tens, we count in twelves….Instead of counting in tens, we should count in dozens.

### Why should we use base 12?

Not only does counting in base-12 allow us to have nicer numbers in division as well as recurring patterns in multiplication, it also paves a smoother path for children to learn basic multiplication.

### How do base 12 number systems work?

The duodecimal system is composed by 12 digits, from 0 to 9, and then two additional digits used to represent 10, and 11. These are Ⅹ, and Ɛ, namely “dek”, and “el”. So, counting the process of counting to 12 works like this: 0, 2, 3, 4, 5, 6, 7, 8, 9, Ⅹ, Ɛ, 10.

What is the value of φ 11?

Euler’s phi function

integer n 1 11
φ(n) 1 10

What is the value of φ 10?

If by phi you mean x which equals x^2–1, then phi = (1+sqrt(5))/2, the 10-digit approximation is 1.618033989.

#### Why did Babylonians use base 60?

“Supposedly, one group based their number system on 5 and the other on 12. When the two groups traded together, they evolved a system based on 60 so both could understand it.” That’s because five multiplied by 12 equals 60. The base 5 system likely originated from ancient peoples using the digits on one hand to count.

What is the base of the Phi numeral system?

Phi numeral system. The phi numeral system ( golden ratio base, golden section base, golden mean base, ϕ -base, base ϕ, phinary, phigital) uses the the golden ratio (symbolized by the Greek letter ϕ) as the base for a non-integer base positional numeral system. Although it is an irrational base, it is not only algebraic,…

What is the value of Phi with two decimals?

Phi (base 12, two decimals) = 1.75 Making the computation .. 1 + (7/12) + (5/144) = 1.618055. It’s amazing the precision we have for Phi with base 12 with just two decimals which would imply in small error propagation when performing manual computation involving this number

## What is a base-φ numeral?

Any non-negative real number can be represented as a base-φ numeral using only the digits 0 and 1, and avoiding the digit sequence “11” – this is called a standard form. A base-φ numeral that includes the digit sequence “11” can always be rewritten in standard form, using the algebraic properties of the base φ — most notably that φ + 1 = φ 2.

## What is 6/5 times Phi^2?

If you’re looking for other interesting ways to relate pi and phi, 6/5 * Phi^2 = 3.1416, which approximates pi. (Contributed by Steve Lautizar.)
