Operators and precedence

Arithmetic binds more tightly than comparison, comparison more tightly than &&, and && more tightly than ||. Parentheses make a different grouping explicit. Logical operators short-circuit.

Integer values also support &, |, ^, and three shifts. >> preserves a sign bit; >>> shifts in zeros. A negative or oversized shift yields zero.

fn main() {
  println(2 + 3 * 4)
  println(10 > 3 && !false)
  println((1 | 2) << 2)
}
