Sexagesimal ↔ Decimal transformation
The calculator enables you to convert the sexagesimal figure (degree,
minute and second) to decimal notation by pressing [
convert the decimal notation to the sexagesimal notation by [ 2nd ]
[ ].
Sexagesimal figure value display is as follow :
Represent 125 degrees (D),
‫׀‬ ‫׀ ׀‬
125 45 30 55
45 minutes(M), 30.55 seconds(S)
(Note) : The total digits of D, M and S and separator marks must be
within 12 digits, or the sexagesimal couldn't be shown
completely.
