Constructive Calculator is an iPhone calculator that computes with exact, arbitrary-precision real numbers. Every result is exact, and you can scroll for as many digits as you want.

A few quick answers

• A result shows a → arrow. That means there are more digits off-screen. Swipe the result sideways, or tap the arrow, to reveal them.
• How do I get more digits? Keep scrolling the result. Digits are computed on demand, without limit.
• Degrees or radians? Use the RAD/DEG switch at the top of the screen.
• Landscape? Rotate the phone for a wider result line and the scientific layout.
