CAACoordinateTransformation_DMSToDegrees: CAACoordinateTransformation_DMSToDegrees

In helixcn/skycalc: Computational Astronomy in R based on PJ Naughter's AA+ library

Description

CAACoordinateTransformation_DMSToDegrees

Usage

CAACoordinateTransformation_DMSToDegrees(Degrees, Minutes, Seconds, bPositive)

Arguments

Degrees	Degrees The degree part of the angular value to convert.
Minutes	Minutes The minute part of the angular value to convert.
Seconds	Seconds The second part of the angular value to convert.
bPositive	bPositive true if the input value corresponds to a non-negative value with false implying the value is positive

Value

Returns the value in degrees which was converted from degrees, minutes and seconds.

Note

To convert the angle 21D 44' 07" you would use DMSToDegrees(21, 44, 7, true).

To convert the angle -12D 47' 22" you would use DMSToDegrees(12, 47, 22, false) or DMSToDegrees(-12, -47, -22, true).

To convert the angle -0D 32' 41" you must use DMSToDegrees(0, 32, 41, false).
