Description
This block sets to 1
the specified bit of its input. The user gives
the bit index in the field Index of Bit with index 0
, as that of the least significant bit.The operation can be summarized
by this expression:
i.e. a bitwise OR
between Input
and
Mask
, an integer of the same length as the input with a value
1
for the bit to set and a value 0
for the other bits.
Data types
The block supports the following types :
Input : scalar. All Scilab's integer type (Data Type parameter).
Output : scalar. Same type than input.
Dialog box
Data Type (3:int32, 4:int16, 5int8, ...)
It indicates the integer type of the input (output) data: between 3 and 8.
Properties : Type 'vec' of size 1.
Index of Bit (0 is least significant)
It indicate the index of the bit to set. The index must be, when the type is:
int32 or uint32: positive and less than 32.
int16 or uint16: positive and less than 16.
int8 or uint8: positive and less than 8.
Properties : Type 'vec' of size 1.
