The currency converter keeps reverting to the last country in the list - very infuriating. I put in Euros and then Sterling but when I put the number into say Euros it changes the Serling to Zambian currency

First, great calculator! Thanks for the tool! ---- Second, if you enter/paste in a value that has illegal characters in it, the calculator breaks. Example: "139,359.99" breaks because of the comma. If you do a find and replace or a regex replace and remove the unusable characters on change, this shouldn't happen. Thanks!

what i said up there

A button that lets you see the multiples/divisibles of a number

When I type 3x*2y it says:"Error. Undefined symbol X".

Every time i wanted to convert $ to other currency, it automatically changed $ to ZMK!!! why??

Enables inverse of tan, cos, sin etc. without many more cumbersome buttons.

Make the digitsAfterPoint variable work. I always get 64 digits after the decimal point.

The x button would help solve the equation/problem
i.e (x+6)squared or 4(2x + 3) +5(x-4)
I know there's a way of doing this on a sheet of paper, but for people to check their answers, i think it would be very useful!

10% of 100.00 is 10, this app shows a total different number, pretty wild.

when a decimal repeats, use this to show that it repeats.

I cannot scroll the conversion type selection. I can select Pressure by clicking the top of the box, which is barely visible, but I cannot select anything below it or read the word Pressure.
