I plugged c AND a OR b into Wolfram Alpha and it gives me (c AND a) OR b. Also c OR a AND b gives me c OR (a AND b) so it does look like in Wolfram Alpha AND has higher precedence than OR. These are logical operators instead of bitwise, but I think they'd follow the same pattern. – cancion witzy araña

Assuming x is signed, need to return 0 for any number not zero, and 1 for zero. A right shift on a signed integer usually is an arithmetical shift in most implementations (e.g. the sign bit is copied over). Therefore right shift x by 31 and its negation by 31. cancion wonder womanWebJavaScript Uses 32 bits Bitwise Operands.
