Notes: A newer version of the Casio fx-100. Similar to the Casio fx-82 series there is a collection of calculator in the fx-100 range. So far I've found mention of the following types:
  • Casio fx-100
  • Casio fx-100A
  • Casio fx-100AU
  • Casio fx-100B
  • Casio fx-100C
  • Casio fx-100D (this one)
  • Casio fx-100MS
  • Casio fx-100MS-2
  • Casio fx-100S
  • Casio fx-100V

This calculator has a 10 digit mantissa and has quite a range of functions. It can perform complex number calculations, BASE-N conversions.

The key that looks like a key to start playing audio or video can be used to correct input errors.

For ENGineers, the calculator has a function to enter and display values using their unit designator. Hence symbols for Femto 'f', Pico 'p', Nano 'n', Micro 'µ', Milli 'm', Kilo 'k', Mega 'M', Giga 'G' and Tera 'T' on the keyboard. They can be used to enter numbers. For example the number 1000 can be entered using 'shift' followed by 'k'.

Next to the normal memory function this calculator also has 9 distinct memories accessable using the 'Kin' and 'Kout' keys. They are also used for statistical operations, and K1...K6 are used to store statistical sums. Which memory location is used for which sum can me seen at the top of the calculator in blue.
