Takes the cube root of a positive or negative number. It works exactly the same as 3×√ or ^(1/3) but is smaller and uses an ending parenthesis. If used on a list, it will return a list with the cube root of each element.
³√(8)
2
³√(2)
1.25992105
³√({1,‾8,27})
{1 ‾2 3}
For complex numbers, the [*http://mathworld.wolfram.com/CubeRoot.html principal cube root] is returned, which may be different from the cube root you'd get for the same real number:
³√(-8) -2 ³√(-8+0i) 1+1.732050808i
Optimization
Never raise something to the one-third power explicitly; use this command instead.
:X^(1/3)→X can be :³√(X→X
