Brackets are used to alter the execution sequence of the operators.

Example: If the operands A, B, C and D have the values 1, 2, 3, and 4,

A+B-C*D

has the result -9 and

(A+B-C)*D

has the result 0.

Function processing is used to execute functions (see Calling Elementary Functions).

During negation - a sign reversal for the value of the operand takes place.

Example: In the example OUT is -4 if IN1 is 4.

OUT := - IN1 ;

In NOT a bit by bit inversion of the operands takes place.

Example: In the example OUT is 0011001100 if IN1 is 1100110011.

OUT := NOT IN1 ;

In exponentiation, ** the value of the first operand (basis) is raised to the power of the second operand (exponent).

Example: In the example OUT is 625.0 if IN1 is 5.0 and IN2 is 4.0.

OUT := IN1 ** IN2 ;

In multiplication, * the value of the first operand is multiplied by the value of the second operand (exponent) .

Example: In the example OUT is 20.0 if IN1 is 5.0 and IN2 is 4.0.

OUT := IN1 * IN2 ;

Note: The MULTIME function in the obsolete library is available for multiplications involving the data type Time.

In division, / the value of the first operand is divided by the value of the second operand.

Example: In the example OUT is 4.0 if IN1 is 20.0 and IN2 is 5.0.

OUT := IN1 / IN2 ;

Note: The DIVTIME function in the obsolete library is available for divisions involving the data type Time.

For MOD the value of the first operand is divided by that of the second operand and the remainder of the division (Modulo) is displayed as the result.

Example: In this example

• OUT is 1 if IN1 is 7 and IN2 is 2

• OUT is 1 if IN1 is 7 and IN2 is -2

• OUT is -1 if IN1 is -7 and IN2 is 2

• OUT is -1 if IN1 is -7 and IN2 is -2

OUT := IN1 MOD IN2 ;

In addition, + the value of the first operand is added to the value of the second operand.

Example: In this example

OUT is 9, if IN1 is 7 and IN2 is 2

OUT := IN1 + IN2 ;

In subtraction, - the value of the second operand is subtracted from the value of the first operand.

Example: In the example OUT is 6 if IN1 is 10 and IN2 is 4.

OUT := IN1 - IN2 ;

The value of the first operand is compared with the value of the second using <. If the value of the first operand is less than the value of the second, the result is a Boolean 1. If the value of the first operand is greater than or equal to the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is less than 10 and is otherwise 0.

OUT := IN1 < 10 ;

The value of the first operand is compared with the value of the second using >. If the value of the first operand is greater than the value of the second, the result is a Boolean 1. If the value of the first operand is less than or equal to the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is greater than 10, and is 0 if IN1 is less than 0.

OUT := IN1 > 10 ;

The value of the first operand is compared with the value of the second operand using <=. If the value of the first operand is less than or equal to the value of the second, the result is a Boolean 1. If the value of the first operand is greater than the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is less than or equal to 10, and otherwise is 0.

OUT := IN1 <= 10 ;

The value of the first operand is compared with the value of the second operand using >=. If the value of the first operand is greater than or equal to the value of the second, the result is a Boolean 1. If the value of the first operand is less than the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is greater than or equal to 10, and otherwise is 0.

OUT := IN1 >= 10 ;

The value of the first operand is compared with the value of the second operand using =. If the value of the first operand is equal to the value of the second, the result is a Boolean 1. If the value of the first operand is not equal to the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is equal to 10 and is otherwise 0.

OUT := IN1 = 10 ;

The value of the first operand is compared with the value of the second using <>. If the value of the first operand is not equal to the value of the second, the result is a Boolean 1. If the value of the first operand is equal to the value of the second, the result is a Boolean 0.

Example: In the example OUT is 1 if IN1 is not equal to 10 and is otherwise 0.

OUT := IN1 <> 10 ;

With &, there is a logical AND link between the operands. In the case of BYTE, WORD and DWORD data types, the link is made bit by bit.

Example: In the examples OUT is 1 if IN1, IN2 and IN3 are 1.

OUT := IN1 & IN2 & IN3 ;

With AND, there is a logical AND link between the operands. In the case of BYTE, WORD and DWORD data types, the link is made bit by bit.

Example: In the examples OUT is 1 if IN1, IN2 and IN3 are 1.

OUT := IN1 AND IN2 AND IN3 ;

With XOR, there is a logical Exclusive OR link between the operations. In the case of BYTE, WORD and DWORD data types, the link is made bit by bit.

Example: In the example OUT is 1 if IN1 and IN2 are not equal. If A and B have the same status (both 0 or 1), D is 0.

OUT := IN1 XOR IN2 ;

If more than two operands are linked, the result with an uneven number of 1-states is 1, and is 0 with an even number of 1-states.

Example: In the example OUT is 1 if 1 or 3 operands are 1. OUT is 0 if 0, 2 or 4 operands are 1.

OUT := IN1 XOR IN2 XOR IN3 XOR IN4 ;

With OR, there is a logical OR link between the operands. With the BYTE and WORD, DWORD data types, the link is made bit by bit.

Example: In the example OUT is 1 if IN1, IN2 or IN3 is 1.

OUT := IN1 OR IN2 OR IN3 ;
