The ^ operator groups left-to-right[.](#1.sentence-1)
|

The operands shall be of integral or unscoped enumeration type[.](#1.sentence-2)

The usual arithmetic conversions ([[expr.arith.conv]](expr.arith.conv "7.4 Usual arithmetic conversions")) are performed[.](#1.sentence-3)

Given the coefficients xi and yi of the base-2 representation ([[basic.fundamental]](basic.fundamental "6.9.2 Fundamental types"))
|
||
of the converted operands x and y,
|
||
the coefficient ri of the base-2 representation of the result r is 1 if either (but not both) of xi and yi is 1,
|
||
and 0 otherwise[.](#1.sentence-4)
|

[*Note [1](#note-1)*:
|

The result is the bitwise exclusive or function of the operands[.](#1.sentence-5)
