Craftulator
Adds a calculator that actually does math. Every button also plays a note.
You know those cheap calculators that beep out a tune when you mash the keys? That's the idea. The number keys are tuned to a scale, so you can play songs on them. It also will play 归零 when reset the calculator.
Using it
Right click the calculator to open it. There's also a keybind, C by default, which works when the calculator is in either hand or worn in an accessory slot.
Numbers, + - × ÷, %, ±, DEL, =. Your keyboard works too if you'd rather type than click. Enter is equals, Backspace deletes, Delete clears.
The notes
Digits 1 through 9 are do re mi and up, in Bb. 0 is the low do underneath them. The operator keys sit an octave or so below all that so they stay out of the way when you're playing something. = gives you a little chime and C plays 归零.
Want it quiet? There's a ♪ key in the bottom left corner that mutes the whole keypad.
Wearing it
Curios, Accessories and Trinkets both get a calculator slot, so you can keep one equipped and open it with the keybind instead of digging through your hotbar.
