Detailed Description

Fixed-point data type: up to 31 decimal digits and a sign bit

See OMG 2011-11-01 CORBA Interfaces v3.2 sections 7.10, 7.11.3.4 See OMG 2011-11-02 CORBA Interoperability v3.2 section 9.3.2.8 See OMG 2012-07-02 IDL-to-C++ Mapping v1.3 section 5.13 This class doesn't exactly match the IDL-to-C++ mapping because it is meant for use inside a union in the IDL compiler and therefore has no constructors. Standards-based middleware libraries such as ORBs and DDSs can wrap this class in a class of their own to provide the exact interface described by the mapping specification.

Member Data Documentation

◆ digits_

Octet ACE_CDR::Fixed::digits_
private

digits_ is not marshaled, the receiver needs to know it from the type information (for example, IDL). The value of digits_ determines how many octets of value_ are masharled.

◆ NEGATIVE

const Octet ACE_CDR::Fixed::NEGATIVE = 0xd
static

◆ POSITIVE

const Octet ACE_CDR::Fixed::POSITIVE = 0xc
static

◆ scale_

Octet ACE_CDR::Fixed::scale_
private

scale_ is not marshaled, the receiver needs to know it from the type information (for example, IDL).

◆ value_

Octet ACE_CDR::Fixed::value_[16]
private

CDR wire format for Fixed: marshaled as an octet array with index 0 as the most significant octet and index n the least significant. Each octet contains two decimal digits except for the last octet (least sig) which has one decimal digit in the high nibble and the sign indicator in the low nibble.
