Bitwise OR
Bitwise OR
is written using a single pipe: |
. Whereas bitwise AND
returns the new number if both bits are set to 1, bitwise OR
returns the new number if either bit is equal to 1 (see Figure 7.5).
When you use the bitwise OR
operator, the result is all 1s (255). You can try this out with code like so:
var a:UInt8 = 0b11111010 //250var b:UInt8 = 0b01010111 //87a|b //255
Figure 7.6 shows another example where both inputs are 0, so the resulting bit is 0 also.
