3.2
2016-03-25
This version adds a new "Key Preview” option. This new option will display a value on applicable keys. Some iOS calculators have this for TVM values but CALC 1 previews the value for TVM, Bonds, all of the Formula Calculators and all of the STO/RCL keys. So now when you tap STO or RCL you see what values are currently stored and the storage variables that are available.
Chain calculations undo is now available for all operators that cause a calculation, and not just = as before. So now you can undo and redo the steps of a long calculation.
New styles: New screens, keys and presets. Millions of custom styles are now available.
A new option, “Key Editing from Calculators" for quick key copy and paste to make it much easier for iPhone users to customize their calculators to be more productive. Just swipe a key to display the Key Editor.
Added History logging to the Form Calculators. This feature now saves all of your Loan, TVM, Amortization, Bonds and Depreciation calculations. The conversion history items save the results and the details of the conversion, including the date of the currency exchange rates.
Changed underflow behavior so in the default Decimal, 2 digits, 0.001 is displayed as 0.001 instead of 1.0E-3. This is common in business and financial calculators.
Added a “swap” button to the UOM and currency conversions. Users now have the option to swap their most used conversion and add more saved conversions.
