degree-from-radian rad &key sexagesimal
radian-from-degree deg &optional (min 0 sexagesimal) (s 0) (sign 1)
radian-from-degree  deg &optional (min 0 sexagesimal) (s 0) (sign 1)  [Function]
Convert a plane angle from degree to radian.

First argument DEG is the number of arc degrees.
Optional second argument MIN is the number of arc minutes.
Optional third argument S is the number of arc seconds.
Optional fourth argument SIGN specifies the sign.

Value is the corresponding angle given in radian.

If two or more arguments are supplied, then MIN and S are sexagesimal
subdivisions of an arc degree.  In this case, DEG, MIN, and S have to
be non-negative numbers and the sign of SIGN, after conversion into a
floating-point number, determines the sign of the angle.
degree-from-radian  rad &key sexagesimal  [Function]
Convert a plane angle from radian to degree.

First argument RAD is the angle given in radian.
If keyword argument SEXAGESIMAL is true, subdivide the return value
 in arc degrees, arc minutes, and arc seconds.  The number of arc
 seconds may be a floating point number with fractions of a second.
 Fourth value is either plus one or minus one specifying the sign
 of the angle.

Value is the corresponding angle given in degree.
