perlop - Perl operators and precedence

NAME

perlop - Perl operators and precedence

SYNOPSIS

Perl operators have the following associativity and precedence, listed from highest precedence to lowest. Note that all operators borrowed from C keep the same precedence relationship with each other, even where C's precedence is slightly screwy. (This makes learning Perl easier for C folks.) With very few exceptions, these all operate on scalar values only, not array values.

    left        ()   terms and list operators (leftward)
    left         ->
    nonassoc    ++  --
    right        **
    right       ! ~ \ and unary + and -
    left        =~ !~
    left        * / % x
    left        + - .
    left        << >>
    nonassoc    named unary operators
    nonassoc    < > <= >= lt gt le ge
    nonassoc    == != <=> eq ne cmp
    left        &
    left        | ^
    left        &&
    left        ||
    nonassoc    .. ...
    right       ? :
    right       = **=  += *= &= <<= &&=  -= /= |= >>= ||= .= %= ^= x=
    left        ,  =>
    nonassoc    list operators (rightward)
    right       not
    left        and
    left        or xor

In the following sections, these operators are covered in precedence order.
