Degrees, Minutes, Seconds to Decimal Degrees

I have been asking around to see if there is an existing class method in C# to do this and it appears not, so I worked out my own methods if anyone is interested or needs them.

// angle or bearing in degrees, minutes and seconds
double angle = 45.2413;

//degrees, minutes and seconds
double degminsec = angle;
// decimal seconds
double decsec = (degminsec * 100 - Math.Truncate(degminsec*100)) / .6;
//degrees and minutes
double degmin = (Math.Truncate(degminsec * 100) + decsec) / 100;
//degrees
double deg = Math.Truncate(degmin);
//decimal degrees
double decdeg = deg + (degmin - deg) / .6;

And this is to go from DecDeg to DMS:

// angle in decimal degrees
double angle = 45.4036;

//decimal degrees
double decdeg = angle;
//integer is minutes and the decimal is decimal seconds
double minsec = (decdeg - Math.Truncate(decdeg)) * 60;
//seconds
double sec = (minsec - Math.Truncate(minsec)) * 60;
//degrees, miutes and seconds
double degminsec = (Math.Truncate(sec) / 10000) + 
(Math.Truncate(minsec) / 100) + Math.Truncate(decdeg);
