How to display a 5-digit number:

For a number with a decimal point, the display will be shifted one digit to the right:

-199.99 will be displayed as -199.9, 4553.6 will be displayed as 4553

For a number without a decimal point, the display will be divided into two alternating phases:

-19999 will be displayed as

45536 will be displayed as

-9999 will be displayed as
