All,
I'm have a bit of an issue understanding the correct logic concerning Optional
Decimals with inidividual operators. Could someone reply to the correctness of
the 2 cases below?
Thanks,
Mike
1) Mandatory Decimal with Individual operators:
Presence: Exponent -> Mandatory, Mantissa -> Mandatory
Operator: Exponent -> Default(0), Mantissa -> Delta
Logic:
Decode_u32( Exponent ); // Bit Required
Decode_u32( Mantissa ); // No Bit Required
2) Optional Decimal with Individual operators:
Presence: Exponent -> Optional, Mantissa -> Mandatory (IFF Exponent is present
in stream)
ExponentPresentInStream = Decode_u32( exponent )// Bit Required for
Exponent
if( ExponentPresentInSteam )
Decode_u32( Mantissa ); // No Bit Required
