The `math` package provides basic constants and mathematical functions.
Import the `math` package:

```js
import "math"
```

## Constants

```js
math.e
math.ln10
math.ln2
math.log10e
math.log2e
math.maxfloat
math.maxint
math.maxuint
math.minint
math.phi
math.pi
math.smallestNonzeroFloat
math.sqrt2
math.sqrte
math.sqrtphi
math.sqrtpi
```

- **math.e** represents the base of the natural logarithm, also known as Euler's number.
- **math.ln10** represents the natural logarithm of 10.
- **math.ln2** represents the natural logarithm of 2.
- **math.log10e** represents the base 10 logarithm of **e** (`math.e`).
- **math.log2e** represents the base 2 logarithm of **e** (`math.e`).
- **math.maxfloat** represents the maximum float value.
- **math.maxint** represents the maximum integer value (`2^63 - 1`).
- **math.maxuint** represents the maximum unsigned integer value  (`2^64 - 1`).
- **math.minint** represents the minimum integer value (`-2^63`).
- **math.phi** represents the [Golden Ratio](https://www.britannica.com/science/golden-ratio).
- **math.pi** represents pi (π).
- **math.smallestNonzeroFloat** represents the smallest nonzero float value.
- **math.sqrt2** represents the square root of 2.
- **math.sqrte** represents the square root of **e** (`math.e`).
- **math.sqrtphi** represents the square root of phi (`math.phi`), the Golden Ratio.
- **math.sqrtpi** represents the square root of pi (π).
