[Year 12 SofDev] 2 digit numbers

[Mark KELLY]

I'd probably argue the point too if I were them  ;-)

When 01, 02, 99 etc are *stored* the number of decimal digits is irrelevant
since they're stored as binary.

The number of digits *shown* in output depends on formatting, e.g. zero
padding, hexadecimal notation etc.

If they were stored as *text*, then storage space would correspond with the
number of ASCII digits.

02 cents' worth
