Elegantly small scientific calculator. At first sight one would
assume this is a plain calculator but a closer look will reveal an
"F"-key to select a number of scientific functions and
The display is oriented left-to-right. When the "F"-key is pressed, an "F" lights up at the leftmost digit. Pressing the "F"-key again will undo this. When a non-zero value is stored in the calculator's memory this is shown by lighting up the right-bottom segment of the leftmost digit (unless the "F" is shown).
There are even exponents for very big (or very small) numbers, leaving 5 digits for accuracy.
On the top-left there is a switch to select the current angular mode.
