Circular R←X○Y
Y
must be numeric. X
must be an integer in the range ¯12 ≤ X ≤ 12
. R
is numeric.
X
determines which of a family of trigonometric, hyperbolic, Pythagorean and complex functions to apply to Y
, from the following table. Note that when Y
is complex, a
and b
are used to represent its real and imaginary parts, while θ
represents its phase.
