If one argument is a scalar or a single-element array, the shape of the result is the
same as that of the other argument. The single element is applied to every element
of the multielement array: "~, ))1.

The I Function: Magnitude, Residue CD
Monadic (One-Argument) Form: Magnitude I B
The magnitude function result is the absolute value of the argument. The argument
can be a numeric scalar, vector, or other array~ The shape of the result is the same
as
that of the argument:

If the argument is an array, the function is extended to each of the elements:

Dyadic (Two-Argument) Form: Residue A I B
The residue function result (when both argument A and argument B are positive) is
the remainder when argument B is divided by argument A. The following rules
apply when using the residue function:
1. If argument A is equal to zero, then the result is equal to argument B:
