1 degree = 60 minutes and 1 minute = 60 seconds.
Thus, M minutes = M/60 degree and S seconds = S/3600 degree.

If Deg is a angle expressed real number, the integer part of angle is degree of angle:  
a = int(Deg) and the rest part r1 is r1 = Deg - a.
Minutes and rest value can be obtained by following formula.
b = int(r1*60), r2 = r1*60 - b
Using same way, seconds can be obtained.
c = r2*60

To express all numbers (degree, minute and second) in one number, shift the location of numbers by multiplying 10000 and 100 to a and b respectively.
A = a*10000, B = b*100

Finally, Degree is converted and expressed as follow:

DMS = A+B+c = int(Deg)*10000 + int((Deg-int(Deg))*60)*100 + ((Deg-int(Deg))*60-int((Deg-int(Deg))*60))*60

DMS = int(Deg)*10000 + int((Deg-int(Deg))*60)*100 + ((Deg-int(Deg))*60-int((Deg-int(Deg))*60))*60
