### Import the math module

```import math
```

### Display the value of pi.

```math.pi
```
```3.141592653589793
```

### Display the value of e.

```math.e
```
```2.718281828459045
```

### Sine, cosine, and tangent

```math.sin(2 * math.pi / 180)
```
```0.03489949670250097
```

### Exponent

```2 ** 4, pow(2, 4)
```
```(16, 16)
```

### Absolute value

```abs(-20)
```
```20
```

### Summation

```sum((1, 2, 3, 4))
```
```10
```

### Minimum

```min(3, 9, 10, 12)
```
```3
```

### Maximum

```max(3, 5, 10, 15)
```
```15
```

### Floor

```math.floor(2.949)
```
```2
```

### Truncate (drop decimal digits)

```math.trunc(32.09292)
```
```32
```

### Truncate (integer conversion)

```int(3.292838)
```
```3
```

### Round to an integrer

```round(2.943), round(2.499)
```
```(3, 2)
```

### Round by 2 digits

```round(2.569, 2)
