units. Such operations convert results with units to the units from the
object in level 1.
Temperature units require special note: see “Working with
Temperature Units” on page 10-10.
The trigonometric operations SIN, COS, and TAN, operate only on
unit objects with planar angular units: radians (r), degrees (°), grads
(gr-Eid), arc-minutes (.arcnin), or arc-seconds (.arcs). The result is a
dimensionless real number.
