ralc's Issues

Remove ellipsis for large numbers

The ellipsis doesn't really add any value. It would be better to just round it.

Save state to localStorage

User's state should be persisted to localStorage to save the session between reloads.

2nd button results in blank page on Chrome and Edge mobile

It seems like everything else works well and installed as a PWA nicely.

Support for international keyboards

Many thanks for this terrific tool! For me, and for many other international users, it would be even more useful if it supported international keyboard layouts. Would that be possible?

At this point, the operator keys '+', '-', '/' etc. appear to be hardcoded to where they are located on a US keyboard. I for one am using a German keyboard (https://en.wikipedia.org/wiki/German_keyboard_layout#/media/File:KB_Germany.svg), where those keys are placed differently, and where I have to press, for example, '(' to get '*'.

Can the keys be picked up "semantically" rather than by their position?

Automatically refresh on new version

When a new version is detected, the app should refresh and immediately start using the latest version.

Depends on #1 - I don't want to refresh the page and interrupt a calculation in progress.

Add modulus operator

Should replace division when alt is enabled

Additional buttons in landscape view

More buttons should appear when in landscape view. Sin/cos/tan, log, etc.

Decimal rounding error

0.99999999999999 is longer than the max buffer size, so it should be rounded to 1 - but instead it erroneously rounds to 0.0000000000000
