Get the integer made up of bytes from the ath to the bth in serial byte key k |
Note:
The function gets a certain byte a or certain bytes from a to b to form an integer.
Parameter:
|
k |
A serial byte key |
|
a |
The ath byte of serial byte k; begin from the first byte when this parameter is absent |

Return value:
Integer
Example:
|
k(4,5,6,8).sbs(2) |
5; get the second byte from serial byte key k(4,5,6,8) to generate an integer. |
|
k(4,5,6,8).sbs(1:3) |
263430; get the bytes from 1 to 3 from serial byte key k(4,5,6,8) to generate an integer. |
|
k(4,5,6,8).sbs(2:) |
329224; get bytes from the second to the end from serial byte key k(4,5,6,8) to generate an integer. |
|
k(4,5,6,8).sbs(:4) |
67438088; get byte from the second to the fourth from serial byte key k(4,5,6,8) to generate an integer. |
