- CLEAR REG is programmable in scientific flavors (did now allow to add this operation to a program) - Advanced Scientific: matrixes may be larger than 33 elements in one dimension (did not allow either dimension to be larger than 33) - Fix number rounding behavior for FRAC, INT, TEST, STO I, CF I, SF I, etc. (should round up but rounded down numbers like 9.99999999999999) Many thanks to F. Vincent for the bug reports and insights!

- Scientific flavors: fix factorial of negative integers (returns Error 0 all the time instead of Lanczos approximation) thanks F. Vincent for the report - Financial advanced: support up to 80 cash flows like newer models, thanks C. Nunes for the report - Internal updates

Internal updates and bugfixes

Small improvement: respond to hard keyboard's Enter (keypad) and right-Delete when run on macOS (thanks J. Bicer for the report)

Fix issue in CF0 operator (it should also accept a value for Nj). Thanks C. Aidinis for the bug report.

Fix in flavor Scientific Basic programming mode (thanks L. Řičánek for the report).

* Internal fixes and updates

Fix in FRAC function (thanks F. Oliveira for the report)

- Sci/Sci advanced: USER A..E hotkeys are handled as GSB A..E and can be programmed as such. Previous behavior was to handle them specially and ignore them in programming mode. - Sci advanced: fixed behavior of matrix instructions STO A..E, STO (I), RCL A..E and RCL (I) when used within in a program. They worked as if USER flag was always on, while they should fix the USER flag status when the instruction was inserted. Thanks V. Brunton for the bug report.

All flavors have now the free (ad-supported) option. So you can experiment with all flavors (financial, scientific and computer programmer's) without cost.

Internal updates and bugfixes

- Paste numbers with configured decimal separator (point or comma) - Hide LCD when in background - Updated libraries

Better handling of multi-touch events during fast typing (thanks to D. Ferrari)

* Financial flavors: fixed issue related to highly negative interest rates (i less than -35%). Aligned IRR with standard: IRR no longer uses "i" as initial guess. Implemented the RCL g R/S key sequence that uses the initial guess. * Scientific Advanced: fixed several issues related to matrixes and complex numbers (thanks to G. Dupont for reporting). Improved SOLVE algorithm (thanks to H. Bieshaar).

1. Facelift in calculator interface. 2. Fixes bug in "Scientific Basic" flavor where the ->P operation could not be used in a program. 3. Fixes bug in "Financial Advanced" flavor where typing decimal point or EEX did not clear the undo annunciator. 4. Faster startup. Ads are no longer shown upon app start; they are shown only when app is resumed. 5. Add dialog to ask for tracking permission for ad purposes. 6. Updated internal libraries.

Updated libraries

1. The calculator memory can now be shared (exported and imported). Learn how to share in https://stendec.io/ctb/touchios/memory.html 2. Fix a rare case where the app is unexpectedly closed when the app is put back to foreground, having been on background.

1. Complete stop when put in background. In this version, even running programs are suspended while the calculator is off-screen. The app should no longer indicate background activity in 'Energy' section of Settings. 2. Flavors can now be purchased directly at App Store. 3. Calculator engines updated.

Fixed bug where flavor would change from scientific to financial when app is restarted.

1) Fixed problem in interface rotation in iPad when layout is locked to portrait 2) Added fast swap buttons to exchange between flavors without opening the Flavors menu.

* Added option "Don't sleep" to Settings. If enabled, screen stays unlocked while app is in use. * Landscape view now works for both landscape-left and landscape-right phone orientations. * Added interstitial ads, shown at startup, for free flavors.

Updated libraries

– Added micro FAQ shown at first startup – Added links to app page and user group at Settings
