What you get

Type a sum and read the answer. Percent, sign change and backspace, with the running calculation shown above the total.

Features

  • A full-screen keypad with everything the desk one has: percent, sign change, backspace and a decimal point.
  • Works the way a pocket calculator does: press an operator mid-sum and the answer so far appears.
  • The running calculation stays visible in a dim line above the total.
  • Results print clean, without trailing zeros, switching to scientific only when a number will not fit.
  • Dividing by zero reads Error until you clear it, and a sum in progress survives a theme change.
