That also reminds me of the note on this page about the Sinclair Scientific calculator's speed:
Due to the simple loop-based algorithms, the speed of the Sinclair Scientific calculator varies from good to horribly slow depending on the values. For instance, sin .1 takes under a second, but sin 1 takes about 7.5 seconds. Arccos .2 takes about 15 seconds. Log and antilog have the overhead of recomputing the constant 229.15, and take about 1 to 2 seconds.
It's worth noting that modern low-end calculators still use very simple processors operating in the kHz range, because they're cheap, ultra-low-power, and sufficiently fast. This does occasionally manifest itself in taking a second or two for computing some more complex functions.
Of course they do. Say, back in 1986 a videogame (Lunolet-4?) used the screen to show the position of the spacecraft between the Earth and the Moon like this: "E L-" - the spacecraft is behind the Moon, "E -L " - the spacecraft between the Earth and the Moon.
