# Free Pascal - Multiplication: *

Multiplication is a matematical operation, it can be used for integers and real numbers.multiplication is an associative operation, therefore order of operands is important. it is necessary to pay attention to the type of output was large enough, otherwise the operation can easily cause an overflow. for example, multiplying two 16-bit numbers we need to put at least 32-bit variable, to prevent overflow.## *

### Description

`par1 * par2`

### Input

- par1 - Any number
- par2 - Any number

### Output

- Result - Any number with the larger type

### Examples

### Free Pascal

Multiplication the possible of use:```
x := 10 * 5; // x=50
y := 100 * 1.2; // y=120
z := (x / 5) * 10;// z=100
```

### Free Pascal

Even one example in what situations we can use the operation multiplication:```
i * $FF
10 * 3.14
(10 - j * 0.5) * 2
```

### Free Pascal

Other pieces of example codes:x * 2 div y

(x * y)

x * 2 / y

i := x * 5;

(x * y)

x := 5 * y;
