In the formulas that follow, the coordinate strings are symbolically represented as follows:¶¶deg                     decimal degrees¶adeg                   absolute value of decimal degrees¶ideg                     integer degrees¶sdeg                   signed integer degree¶min                      real-number minutes¶imin                      integer minutes¶sec                      real-number seconds¶lathem, lonhem    hemisphere abbreviation¶¶
The degree and hemisphere parameters remain unchanged in this conversion (both forward and reverse) and also retain their position in their respective coordinate strings.¶¶Forward calculation from DMH representation to DMSH representation:¶imin = INT(min)¶sec = (min - imin) * 60¶¶Reverse calculation from DMSH representation to DMH representation:¶min = imin + (sec / 60)
