A basic Line input　arithmetical calculator !
This app will help you do a little calculation of the day.
It is inferior to the windows10 standard calculator app, but it has the following functions.
· Calculation of consumption tax
· Discount calculation
· Change button style
Standard · Rounded corners · pork · cat · apple · cup · heart · frog
· Change of currency type
Convenient for US-JAPAN trip
· Remaining calculation
Although it is assumed to be used for mobile, when using a keyboard on a PC,
RCL -> R
OFF -> O
TAX -> T
= -> = or enter
And others are the same as on the keyboard display.
I do not have a US keyboard, so I have not confirmed it.
