Binary and Bitwise Operations
The table that follows summarizes the interpretation of all binary operators in Stateflow action language. Table order gives relative operator precedence; highest precedence (10) is at the top of the table. Binary operators are evaluated left to right (left associative).
You can specify that the binary operators &, ^, |, &&, and || are interpreted as bitwise operators in Stateflow generated C code for a chart or for all the charts in a model. See these individual operators in the table that follows for specific binary or bitwise operator interpretations.
| Example |
Precedence |
Description |
a * b |
10 |
Multiplication |
a / b |
10 |
Division |
a %% b |
10 |
Modulus |
a + b |
9 |
Addition |
a - b |
9 |
Subtraction |
a >> b |
8 |
Shift operand a right by b bits. Noninteger operands for this operator are first cast to integers before the bits are shifted. |
a << b |
8 |
Shift operand a left by b bits. Noninteger operands for this operator are first cast to integers before the bits are shifted. |
a > b |
7 |
Comparison of the first operand greater than the second operand |
a < b |
7 |
Comparison of the first operand less than the second operand |
a >= b |
7 |
Comparison of the first operand greater than or equal to the second operand |
a <= b |
7 |
Comparison of the first operand less than or equal to the second operand |
a == b |
6 |
Comparison of equality of two operands |
a ~= b |
6 |
Comparison of inequality of two operands |
a != b |
6 |
Comparison of inequality of two operands |
a <> b |
6 |
Comparison of inequality of two operands |
a & b |
5 |
One of the following:
|
a ^ b |
4 |
One of the following:
|
a | b |
3 |
One of the following:
|
a && b |
2 |
Logical AND of two operands |
a || b |
1 |
Logical OR of two operands |
