ARITHMETIC OPERATIONS
- a
+ a
a && b (logical AND; not audio-rate)
a || b (logical OR; not audio-rate)
a + b
a - b
a * b
a / b
DESCRIPTION
where the arguments a and b may be further expressions.
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:
-
* 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.
-
+ and - bind more strongly than &&, which in turn
is stronger than ||:
a && b - c || d
is taken as (a && (b-c)) || d
-
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.
