||

|| — Logical OR operator.

Description

Arithmetic operators perform operations of change-sign (negate), don't-change-sign, logical AND logical OR, add, subtract, multiply and divide. Note that a value or an expression may fall between two of these operators, either of which could take it as its left or right argument, as in


a + b * c.
      

In such cases three rules apply:

1. * and / bind to their neighbors more strongly than + and −. Thus the above expression is taken as

  
a + (b * c)
      

with * taking b and c and then + taking a and b * c.

2. + and bind more strongly than &&, which in turn is stronger than ||:

  
a && b - c || d
      

is taken as

  
(a && (b - c)) || d
      

3. When both operators bind equally strongly, the operations are done left to right:

  
a - b - c
      

is taken as

  
(a - b) - c
      

Parentheses may be used as above to force particular groupings.

Syntax

a || b  (logical OR; not audio-rate)

where the arguments a and b may be further expressions.
