bytestoshort(Input1, Input2) - used to pack 2 bytes in the short (Output = Input<<8+Input2).

shorttobyte(Input1, Input2) - used to unpack short value in 2 bytes (Output = Input[Input2]).

shortstoint(Input1, Input2) - used to pack 2 shorts in the int (Output = Input<<16+Input2).

inttoshort(Input1,Input2) - used to unpack int value in 2 shorts (Output = Input[Input2]).

readbit(Input1, Input2) - used to read bit of the input value (Output = Input[Input2]).

setbit(Input1, Input2) - used to set bit of the input value (Output = Input | 1<<Input2).

resetbit(Input1,Input2) - used to reset bit of the input value (Output = Input & ~(1<<Input2)).

 

Example:

int a = setbit(6, 0);

print(a);

Response:

a = 7;
