# Arithmetic Operators

### + Operator

Used to sum two numbers.

**Syntax:** *result* = *operand1* **+** *operand2*

**Remarks:** If one or both operands are **Null** expressions, *result* is a **Null**. If both operands are Empty, *result* is an **Integer**. However, if only one operand is Empty, the other operand is returned unchanged as *result*.

**Example:** This example adds input tag 1, input tag 2 and 20.5.

Result = GD(1) **+** GD(2) **+** 20.5

### - Operator

Used to find the difference between two numbers.

**Syntax:** *result* = *operand1* **-** *operand2*

**Remarks:** If one or both operands are **Null** expressions, *result* is a **Null**. If an operand is Empty, it is treated as if it were 0.

**Example:** This example subtracts input tag 2 from input tag 1.

Result = GD(1) **-** GD(2)

### * Operator

Used to multiply two numbers.

**Syntax:** *result* = *operand1* ***** *operand2*

**Remarks:** If one or both operands are **Null** expressions, *result* is a **Null**. Any operand that is Empty is treated as 0.

**Example:** The flow is the product of Input tag 1 (Total Flow) and Input tag 2 (Concentration).

ChemicalFlow = GD(1) ***** GD(2)

### / Operator

Used to divide two numbers and return a floating-point result.

**Syntax:** *result* = *operand1* **/** *operand2*

**Remarks:** If one or both operands are **Null** expressions, *result* is a **Null**. Any operand that is Empty is treated as 0.

**Example:** The sum of two tags is divided by 1000.

Result = (GD(1) + GD(2))**/**1000

### ^ Operator

Used to raise a number to the power of an exponent.

**Syntax:** *result* = *number* **^** *exponent*

**Remarks:** The *number* operand can be negative only if *exponent* is an integer value. When more than one exponentiation is performed in a single expression, the **^** operator is evaluated as it is encountered from left to right. If either *number* or *exponent* is a **Null** expression, *result* is also a **Null**.

**Example:** This example squares (n^2) the value for Input tag 1.

Result = GD(1) **^** 2
