Purpose (one Line)

Convert from degrees, minutes, and seconds to radians.

Description

Calling Sequence

dmstorad, sign, deg, min, sec, radians

Inputs

sign : Sign associated with the inputs. Must be -1, or +1.
deg : Degrees. No restrictions.
min : Minutes. 0 <= min < 60.
sec : Seconds. 0.0 <= sec < 60.0.
If more than one of these are vectors, they must be the same length.
A mixture of scalar and vector input parameters is equivalent to all three
inputs being vectors: The scalar inputs are treated as replicated vectors.

Optional Input Parameters

Outputs

radians : Converted angle in radians.

Procedure

The input declination is in four parts. The sign is carried as a separate
value, to make angles near zero behave correctly.
