Algebra Functions
Algebra built-in functions perform common power and root calculations.
cbrt(x)
Returns the cube root of a number.
| Argument | Type | Description |
|---|---|---|
| `x` | number | Input value. |
Returns: number.
Example:
cbrt(27); // 3
cube(x)
Returns `x * x * x`.
| Argument | Type | Description |
|---|---|---|
| `x` | number | Input value. |
Returns: number.
Example:
cube(3); // 27
pow(base, exponent)
Raises `base` to `exponent`.
| Argument | Type | Description |
|---|---|---|
| `base` | number | Base value. |
| `exponent` | number | Exponent value. |
Returns: number.
Errors:
- `0` raised to a negative exponent is invalid.
- A negative base with a non-integer exponent is not supported.
- Overflow is reported as an error.
Example:
pow(2, 8); // 256
sqr(x)
Returns `x * x`.
| Argument | Type | Description |
|---|---|---|
| `x` | number | Input value. |
Returns: number.
Example:
sqr(12); // 144
sqrt(x)
Returns the square root of a number.
| Argument | Type | Description |
|---|---|---|
| `x` | number | Input value. Must be greater than or equal to zero. |
Returns: number.
Example:
sqrt(25); // 5
