bitor

Bitwise OR of two fi objects

Syntax

c = bitor(a,b)

Description

c = bitor(a,b) returns the bitwise OR of fi objects a and b. The output is determined as follows:

  • Elements in the output array c are assigned a value of 1 when the corresponding bit in either input array has a value of 1.

  • Elements in the output array c are assigned a value of 0 when the corresponding bit in both input arrays has a value of 0.

The numerictype properties associated with a and b must be identical. If both inputs have a local fimath, their local fimath properties must be identical. If the numerictype is signed, then the bit representation of the stored integer is in two's complement representation.

a and b must have the same dimensions unless one is a scalar.

bitor only supports fi objects with fixed-point data types.

Examples

The following example finds the bitwise OR of fi objects a and b.

a = fi(-30,1,6,0);
b = fi(12, 1, 6, 0);
c = bitor(a,b)

c =
 
   -18

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 6
        FractionLength: 0

You can verify the result by examining the binary representations of a, b and c.

binary_a = a.bin
binary_b = b.bin
binary_c = c.bin

binary_a =

100010

binary_b =

001100

binary_c =

101110
