[boost] What does "ll" stand for?

This is for the "ll" function defined for quaternions and octonions.  The
function returns the 1-norm of its argument.  Does anyone know what the "ll"
name stands for?  I finally figured out that "sup" (the infinity-norm) most
likely stands for "supremum".  (BTW, "abs" is the 2-norm.  The "norm"
function isn't actually in this system, despite the name!)
