ARITHMETIC OPERATIONS</H2>
<PRE> - a
+ a
a && b (logical AND; not audio-rate)
a || b (logical OR; not audio-rate)
a + b
a - b
a * b
a / b</PRE>

<U>DESCRIPTION</U></H4>
where the arguments a and b may be further expressions.
<P>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
<PRE> a + b * c.</PRE>
In such cases three rules apply:
<UL>
<LI>
<B>*</B> and <B>/</B> bind to their neighbors more strongly than + and
-. Thus the above expression is taken as</LI>
<P><TT>a + (b * c),</TT>
<P>with * taking b and c and then + taking a and b * c.
<LI>
<B>+</B> and <B>-</B> bind more strongly than &&, which in turn
is stronger than ||:</LI>
<P><TT>a && b - c || d</TT>
<P>is taken as <TT>(a && (b-c)) || d</TT>
<LI>
When both operators bind equally strongly, the operations are done left
to right:</LI>
<P><TT>a - b - c</TT>
<P>is taken as <TT>(a - b) - c</TT>.</UL>
Parentheses may be used as above to force particular groupings.
