Math Cubic Root function?

[JulesV]

As the title says, I couldn't find a cubic root function equivalent to std::cbrt

Any ideas?

[d.healey]

@JulesV Math.pow(x, 1/3);?

[JulesV]

@d-healey Yes, that's it, thanks. I had to use If/else Statement for negative values, though.

@JulesV abs is your friend here.

[d.healey]

@JulesV What about something like this

inline function cubeRoot(x)
{
    return x < 0 ? -Math.pow(-x, 1/3) : Math.pow(x, 1/3);
}

@d-healey or this

return Math.sign(x) * Math.pow(Math.abs(x), 1/3);

But a benchmark shows no difference in efficiency
