"The Golden Ratio is just as useful as Pi. Your calculator is just what I was looking for. I could do the same thing with a Calculator or a Slip Stick but your App is SO much faster. THANK YOU"

The ratios

The golden ratio is a special number approximately equal to 1.618. It appears many times in geometry, art, architecture and other areas, often with pleasing results. It has been called divine proportion due to its numerous occurrences in nature.

The silver ratio arises in many mathematical and geometric expressions. The name is an allusion to the golden ratio; analogously to the way the golden ratio is the limiting ratio of consecutive Fibonacci numbers, the silver ratio is the limiting ratio of consecutive Pell numbers. You can cut A-series paper in half repeatedly and maintain the silver ratio.

The bronze ratio is often used in origami for making shapes with 30°, 60° or 120° angles.

The Yamato ratio is the ratio used for the face of a Buddha statue, Japanese architecture, sculptures and flower arrangements.

All these ratios make the app incredibly useful while doing design or layout work.
