The Casio AL-10, along with the AL-8, was the first calculator to accept and display fractions. They were also the first pocket calculators with a built-in standard deviation programme. They could also display time in hours, minutes and seconds.

The calculator had a six-mode program switch which allowed you to switch between square root function, simultaneous addition of two columns of figures, the ability in divisions to give the integer number and the remainder, fraction mode, handling of sexagesimal (base 60) calculations, and standard deviation.

The difference between the AL-10 and the AL-8 was that the AL-10 had a 10-digit display while the AL-8 had an eight-digit display. Both had green vacuum fluorescent displays (VFD).

This electronic calculator is complete with original box and manual.
