According to Wolfram MathWorld [0], when talking about principal curvatures, $\kappa_1$ is the maximum and $\kappa_2$ is the minimum normal curvature.
However, I also noticed that Grasshopper documentation [1] defines $K^1$ as the principal direction corresponding to the absolute maximum principal curvature.
This confused me, so I would like to ask whether the principal curvatures $\kappa_1, \kappa_2$ represent the absolute minimum/maximum or just plain minimum/maximum of normal curvature?
What would be the correct value of $\kappa_{1}$ and $\kappa_{2}$ in the example below? Assume $\kappa_{min}$ is the minimum (non-absolute) normal curvature and $\kappa_{max}$ is the maximum (non-absolute) normal curvature? $$ \kappa_{max} = -0.52\\ \kappa_{min} = -4.84\\ \kappa_1 = \text{$\kappa_{min}$ or $\kappa_{max}$?}\\ \kappa_2 = \text{$\kappa_{min}$ or $\kappa_{max}$?} $$
EDIT: By "absolute", I meant the absolute value of a number.
