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¶¶
In this conversion the parameter values remain unchanged but are re-ordered.¶¶For the forward calculation from HDMS representation to DMSH representation, for each of latitude and longitude re-order the fields:¶          from  	hem, ideg, imin, sec¶          to       	ideg, imin, sec, hem¶¶For the reverse calculation from DMSH representation to HDMS representation, for each of latitude and longitude re-order the fields:¶          from  	ideg, imin, sec, hem ¶          to       	hem, ideg, imin, sec
