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