3.6.11 Binary operators
Binary operators are written between the pair of subexpressions they operate on.
Binary operators have lower precedence than unary operators. Binary operators appear
in this section in order of precedence.
Note
The order of precedence is not the same as in C, see Operator precedence on page 3-24.
Multiplicative operators
Multiplicative operators have the highest precedence of all binary operators. They act
only on numeric expressions.
Table 3-5 shows the multiplicative operators.
String manipulation operators
Table 3-6 shows the string manipulation operators.
In the two slicing operators
LEFT
and
RIGHT
:
•
A
must be a string
•
B
must be a numeric expression.
In
CC,
A
and
B
must both be strings.
