abs - compute the absolute value
val.abs()
The abs()
method computes the absolute value
of the given val. If val is an arithmetic scalar or if
it a packed arithmetic array, the result has the same type as
val. If val is a List
or
Array
and if each element of val is an
arithmetic type, then a packed array will be created based on packing
rules (see pack for more information).
