13 -
For example, the decimal number 4660 has (12 34) as its hexadecimal representation and is recorded as (12
34).
7.2.3 Both-byte
orders
A numerical value represented by the hexadecimal representation (wx yz) shall be recorded in a four-byte field
as (yz wx wx yz).
NOTE 11
For example, the decimal number 4660 has (12 34) as its hexadecimal representation and is recorded as (34 12
12 34).
7.3
32-bit numerical values
A numerical value represented in binary notation by a 32-bit number shall be recorded in a field of a descriptor in
one of the following three formats. The applicable format is specified in the description of the descriptor fields.
7.3.1
Least significant byte first
A numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in a four-byte
field as (yz wx uv st).
NOTE 12
For example, the decimal number 305419896 has (12 34 56 78) as its hexadecimal representation and is
recorded as (78 56 34 12).
7.3.2
Most significant byte first
A numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in a four-byte
field as (st uv wx yz).
NOTE 13
For example, the decimal number 305419896 has (12 34 56 78) as its hexadecimal representation and is
recorded as (12 34 56 78).
7.3.3 Both-byte
orders
A numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in an eight-
byte field as (yz wx uv st st uv wx yz).
NOTE 14
For example, the decimal number 305419896 has (12 34 56 78) as its hexadecimal representation and is
recorded as (78 56 34 12 12 34 56 78).
7.4
Character sets and coding
7.4.1
d-characters and a-characters
Except as specified in 7.4.4, the characters in the descriptors shall be coded according to ECMA-6 (see
Appendix A).
The 37 characters in the following positions of the International Reference Version are referred to as
d-characters:
3/0 to 3/9
4/1 to 5/10
5/15
The 57 characters in the following positions of the International Reference Version are referred to as
a-characters:
2/0 to 2/2
2/5 to 2/15
3/0 to 3/15
4/1 to 4/15
5/0 to 5/10
5/15
