Hexidecimal numbers are represented with all letters in upper-
case with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’).
Numbers not indicated by an ‘h’ or ‘b’ are decimal.
