φ digit calculator tool
What is a φ digit calculator?

This is an online browser-based utility for generating a list of digits of the golden ratio. It's said that two objects are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two objects. Roughly speaking, this proportion can be expressed as 62% to 38%. The golden ratio is denoted by the Greek letter phi (Φ or φ) and often appears in science and nature. Many other names are used for the phi constant, in particular, golden mean, golden number, golden section, and lesser-known – extreme and mean ratio. The golden section can be calculated by solving the quadratic equation φ² - φ - 1 = 0. It has two solutions: φ = (1+√5)/2 (positive constant) and φ = (1-√5)/2 (negative constant). In this tool, you can calculate both the positive and negative golden proportion and get any number of φ digits, up to one million values. You can also get only digits of the ratio, without the whole number part (either "1." for positive phi or "-0." for negative), and optionally set a separator between φ digits. That's numberwang!

1000 Golden Ratio Digits

In this example, we find the first one thousand digits of the positive golden number, that is, of the constant φ = (1+√5)/2.
