∥ (parallel to)
Checks if two vectors are parallel.
Syntax

u ∥ v

u
andv
are vectors of the same dimension

Description
If u
and v
are vectors of the same dimension, then u ∥ v
is true
iff u
and v
are parallel, that is, iff there exists a scalar κ
such that u = κ⋅v
or v = κ⋅u
.
Notes
The ∥
operator is implemented by the AreParallel
function. This function also supports a third argument specifying the epsilon to use for floatingpoint comparison.
