cbrt

class brainunit.math.cbrt(x, **kwargs)

Compute the cube root of each element.

When the input carries a unit, the resulting unit is the cube root of that unit (e.g. meter ** 3 becomes meter).

Parameters:

x (saiunit.Quantity | Array | ndarray | bool | number | bool | int | float | complex) – The values whose cube-roots are required.

Returns:

y – An array of the same shape as x, containing the cube root of each element. If x carries a unit, the result is a Quantity whose unit is x.unit ** (1/3).

Return type:

saiunit.Quantity | Array

Examples

>>> import saiunit as u
>>> q = u.math.array([8.0, 27.0]) * (u.meter ** 3)
>>> u.math.cbrt(q)  # Quantity with unit meter
