A Complex Calc1.0.19 - App Store

A Complex Calc is built for fast complex-number work without losing the tools you need for serious math.

Use scientific functions quickly and check floating-point results in rectangular and polar form.

Reuse past results from history, work with built-in constants, and keep advanced tools close while solving everyday and technical calculations.

Version History - Fixed the constants panel so it opens and closes reliably, including after rotation or an interrupted transition.
- Improved complex-expression entry for adjacent terms, signed denominators, scientific notation, and incomplete exponents.
- Made calculation history safer and more reliable across saves, migrations, corrupted data, and exact entry deletion.
- Corrected published physical constants and localized constant names.
- Fixed unit-conversion edge cases and made binary operations reject invalid input predictably.
- Improved calculator, history, and constants layouts across rotation, safe areas, and interrupted transitions.
- Fixed widget startup, bundled resources, paste, and update handling.
- Smoothed button, gradient, and scrolling-label presentation while avoiding duplicate layers and gestures.
- Improved the iPad launch presentation and credit-screen transitions. 1.0.19 Aug 20 - Expressions now stay visible until you press equals, making complete calculations easier to review and edit.
- Chained operations preserve the full floating-point result for more accurate follow-up calculations.
- Polar conversion now works with complete complex expressions and preserves follow-up operations.
- Complex trigonometric and inverse-function results now respect degree and radian modes consistently.
- Improved factorial handling, principal values, and error messages for invalid input, overflow, and shifts.
- Constants and history now replace completed or failed results cleanly, including localized decimal input. 1.0.18 Aug 5 - Fixed an issue where complex numbers like 41i could be displayed incorrectly while typing.
- Updated fractional results to display as rounded decimals, matching standard calculator behavior. 1.0.17 Jun 30 - Fixed an issue where complex numbers like 41i could be displayed incorrectly while typing. 1.0.16 Apr 16 - Better exact arithmetic and complex calculation handling.
- Smoother switching between calculator layouts.
- Improved history, constants, and overall stability. 1.0.15 Apr 14 This update improves calculation accuracy, reliability, and scientific features.

- Improved support for very large numbers with more exact results in many real and complex operations
- Better handling of scientific calculations, including polar representation
- Fixed issues with powers, factorials, parentheses validation, and malformed expressions
- Improved precision for exact arithmetic and rational results
- Better history reliability and several stability fixes
- General bug fixes and internal improvements for a smoother experience 1.0.14 Mar 21 This update improves calculation accuracy, reliability, and scientific features.

General bug fixes and internal improvements for a smoother experience 1.0.13 Mar 20 Fixed a crash for all iPhones and iPad without safe area 1.0.12 10/19/2019 Adaptations for Dark Mode 1.0.11 10/05/2019 Fixed a bug for the Widget extension 1.0.10 10/03/2019 Fixed a bug for France, Italy and Spain 1.0.9 05/23/2019 Reverted order of history (from most recent to oldest)

Swapped top line of buttons with the last one (users feedback says is a more natural layout) 1.0.8 05/19/2019 Fixed a bug afflicting iPhone 6 or iPhone 6s models. The last result was partially hidden behind the constants buttons. 1.0.7 01/20/2019 Added panel with some common mathematical and physics constants. 1.0.6 01/12/2019 Added a Today Widget to do basic calculations without unlocking the phone (see new screenshot).
Fixed minor bugs. 1.0.5 08/24/2018 Fixed a bug occurring with closing parentheses and implicit multiplying operation.
Credit to fellow developer Mario Monaco for reporting issue. 1.0.4 07/30/2018 Improvements after collecting some feedback:
- Increased speed in buttons animation
- Increased speed in credit view animation
- Changed gradient color for operation buttons
- Added a swipe gesture to open or close the history view
- Added haptic feedback on the 'copy' button in the history entries (3D Touch screens only) 1.0.3 07/22/2018 Fixed a bug that prevented the circular menù in the basic view to be shown. 1.0.2 06/02/2018 Fixed a crash
Fixed a minor bug
Reduced tap area of the bottom right button in the basic calculator. It's near the equal sign, a 'buffer' area is needed to prevent accidental taps. 1.0.1 04/25/2018 1.0 04/21/2018
