## 1 Introduction

A number of arithmetic expressions are supported, all of which work on numeric types (Integer/Long, and Decimal).

## 2 Multiplication

Multiplies two numbers.

### 2.1 Input parameters

- First number Type: Integer/Long, Decimal
- Second number Type: Integer/Long, Decimal

### 2.2 Output

If the two inputs are both of type Integer/Long, the result is of type Integer/Long.

If any of the two inputs is of type Decimal, the result is of type Decimal.

## 3 Division

Divides two numbers. You can use either the `div`

or colon ( : ) syntax, as can be seen below in the examples. The colon ( : ) syntax is inspired by the divide symbol `รท`

. We cannot use the more conventional slash ( / ) syntax because that would conflict with the slash we use for separating objects and members.

### 3.1 Input Parameters

- First number Type: Integer/Long, Decimal
- Second number Type: Integer/Long, Decimal

### 3.2 Output

If any of the two inputs is of type Decimal, the result is of type Decimal.

`div`

syntax:

```
3 div 5
```

results in:

```
0.6
```

`:`

syntax:

```
12 : 3
```

results in:

```
4.0
```

### 3.3 Warning

The result of a division is only an approximation if it has an infinite decimal expansion. For example:

```
3 : 7
```

results in:

```
0.4285714285714285714285714285714286
```

The consequence of this is that if you continue a calculation with the results of a division, the results might be unexpected. For example:

```
(3 : 7) * 7
```

results in:

```
3.0000000000000000000000000000000002
```

and:

```
ceil((3 : 7) * 7)
```

in:

```
4
```

It is therefore recommended to do division operations last.

## 4 Modulo

Calculates the remainder of the division of one number by another. In other words, m modulo n corresponds to: m = p + k*n, where p is the result of the operation m modulo n.

### 4.1 Input Parameters

- First number Type: Integer/Long, Decimal
- Second number Type: Integer/Long, Decimal

### 4.2 Output

If the two inputs are both of type Integer/Long, the result is of type Integer/Long.

If any of the two inputs is of type Decimal, the result is of type Decimal.

```
23 mod 5
```

results in an Integer/Long with value:

```
3
```

## 5 Addition

Adds two numbers.

For more information, see String function calls.

### 5.1 Input Parameters

- First number Type: Integer/Long, Decimal
- Second number Type: Integer/Long, Decimal

### 5.2 Output

If the two inputs are both of type Integer/Long, the result is of type Integer/Long.

If any of the two inputs is of type Decimal, the result is of type Decimal.

```
-3 + 4
```

results in an Integer/Long with value:

```
1
```

## 6 Subtraction

Subtracts the second input from the first.

### 6.1 Input Parameters

- First number Type: Integer/Long, Decimal
- Second number Type: Integer/Long, Decimal

### 6.2 Output

If the two inputs are both of type Integer/Long, the result is of type Integer/Long.

If any of the two inputs is of type Decimal, the result is of type Decimal.

```
5 - 4
```

results in an Integer/Long with value:

```
1
```
