What's new

- Increased range for very small numbers. Full range of numbers is now between 1E127 and 1E-128 with up to 12 digits of precision.

- Improved Memory buttons behavior for faster entry:
-- After M+, M-, MS, or MR is pressed, if a number is entered, the Input is automatically cleared, otherwise the Input is appended.
-- When MR is pressed, if a number is immediately to the left of the cursor, the Input is automatically cleared, otherwise the Input is appended.

- App now remembers last button pressed. This allows you to pickup where you left off after relaunching, even if the app is cleared from memory between uses.

- Fixes bug when using +/- button in regions where the thousands separator is a space.
