Vector types with unit (#27 - #28)

27. Float array with unit

After the byte with value 27, the array types have a 32-bit int indicating the number of values in the array that follows. This int is itself not preceded by a byte indicating it is an int. Then a one-byte unit type follows (see the table in Coding of units ) and a one-byte display type (see Display types for units). The internal storage of the values that are transmitted after that always use the SI (or standard) unit. As an example: when we send an array of two durations, 2.0 minutes and 2.5 minutes, this is coded as follows (assuming big-endian encoding):

|27|0|0|0|2|25|7|
|0x40|0x00|0x00|0x00|
|0x40|0x20|0x00|0x00|

In this illustration, the 11 bytes have been divided over three lines for readability. The serialized data may not contain such line breaks.

28. Double array with unit

After the byte with value 28, the array types have a 32-bit int indicating the number of values in the array that follows. This int is itself not preceded by a byte indicating it is an int. Then a one-byte unit type follows (see the table in Coding of units ) and a one-byte display type (see Display types for units). The internal storage of the values that are transmitted after that always use the SI (or standard) unit. As an example: when we send an array of two durations, 21.2 minutes and 21.5 minutes, this is coded as follows (assuming big-endian encoding):

|28|0|0|0|2|25|7|
|0x40|0x35|0x33|0x33|0x3|0x33|0x33|0x33|
|0x40|0x35|0x80|0x00|0x00|0x00|0x00|0x00|

In this illustration, the 23 bytes have been divided over three lines for readability. The serialized data may not contain such line breaks.
