Elektronika B3-02

This calculator has had a rather nasty fall, as can be seen by the damage to the back of the unit. At first this machine was not working, but by soldering a (very thin) loose wire, it came back to life!

Handling of decimals is quite strange; the first number must be input with the number of decimal places required in the final result. That is, for 2 digit precision on 9 / 3, you must enter 9,00 / 3 = Once precision has been set (entry of the first number), it remains that precision. You can't do 9 / 3,0 ... key entry of decimals is "locked out" until you press C, allowing another "first number". In precision handling, and in leading 0s, this machine is similar to the 4-71b, except it has large 0s.

Leading zeroes are not suppressed, and extend to the left (the number is right-justified). Overflow is indicated in the leftmost digit by a lowercase n occupying segments 1,2,3.
