+
+ Calculator for QMK-based keyboard by MWWorks, https://mwworks.uk
+ This is free, usual disclaimers, don't use it to calculate megaton yields, surgery plans, etc
+
+ I did not plan to reinvent the wheel for this - I figured surely somebody somewhere has working calculator code?
+ Found lots but none that actually work like you expect a calculator to, hence DIYing it
+
+ As such, this is probably a bit janky, especially as I am a bit of a hack at C
+ Seems to be working well, with occasional glitchs, solved by clearing it
+ And some occasional floating-point issues - eg get a long decimal rather than the whole number you were expecting
+ Feel free to fix it! I think it needs to detect the precision of the two operands and then figure out what the precision of the result should be

+[Proto Album](https://imgur.com/a/QVtU7hV)
+
+A 4x5 layout numpad with rotary encoder, LED indicator and OLED screen, featuring a basic calculator inside the OLED screen. The PCB supports both hotswap and solderable switch. Currently the PCB and case can only be purchased in Indonesia.
+
+* Keyboard Maintainer: [ohchiko](https://github.com/ohchiko)
+* Hardware Supported: Rubi PCB Rev. A, ATMega32u4
+* Hardware Availability: Local Indonesia GB.
+
+Make example for this keyboard (after setting up your build environment):
+
+ make rubi:default
+
+Flashing example for this keyboard:
+
+ make rubi:default:flash
+
+To put this keyboard into bootloader mode (for flashing firmware), simply activate layer 3 and press the middle key (key "5" on the proto picture) on the default keymap.
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
