Hi

I have a project from digital fundamentals class to build a simple

calculator circuit that performs add function, subtract function and

display results(21/2 digit).

here is my question,

what does 21/2 digit really mean? is that a name of a display device?

or 21 inputs and 2 outputs?

thank you for sharing your knowledges

The reference to 2 and 1/2 digits typically means that the display has three digit positions with the two right most digits in the display capable of taking on the values 0 through 9 and the remaining leftmost digit is restricted to the digits 0 or 1 and in some displays the leftmost digit can display a 2. The reference to 1/2 digit refers to the fact that the leftmost digit is limited in the range of numbers it can display.
