Hooray for seven-segment LED displays! Or LCD, if it's that kind of calculator, but for my money the old red LED ones back in the 1970s were unbeatable for sheer grooviness. Or cheap nostalgia value. Flip a coin, eh?

The decimal point creates a space, naturally.

So here's what that'd look like in practice:

     _               _       
    | | |_    o |_  |_ |  |  
    |_| | |     | | |_ |_ |_ 

Note that some displays would have a serif of sorts on the '7'. That's a bummer, but it doesn't entirely spoil the effect:

     _               _        
    | | |_    o |_  |_  |   |  
    |_| | |     | | |_  |_| |_|
