2.1.4.1. Bit-string Operations on Integer Types

The priorities of the binary bit-wise operations are all lower than the numeric operations and higher than the comparisons; the unary operation `~' has the same priority as the other unary numeric operations (`+' and `-').

This table lists the bit-string operations sorted in ascending priority (operations in the same box have the same priority):

Operation

Result --- Notes

x | y

bitwise or of x and y

---

x ^ y

bitwise exclusive or of x and y

---

x & y

bitwise and of x and y

---

x << n

x shifted left by n bits --- (1), (2)

x >> n

x shifted right by n bits --- (1), (3) @hline@hline

~x

the bits of x inverted

(1)

Negative shift counts are illegal.

(2)

A left shift by n bits is equivalent to multiplication by pow(2, n) without overflow check.

(3)

A right shift by n bits is equivalent to division by pow(2, n) without overflow check.
