Sexagesimal ↔ Decimal form conversion

The calculator enables you to converts the sexagesimal figure (degree,

minute and second) to decimal notation by pressing [ ] and converts the decimal notation to the sexagesimal notation by [2ndF]

[ ].

Sexagesimal figure value display is as follow :

12□ 45 I 30 I I 5

Represent 12 degrees, 45 minutes, 30.5 seconds

(Note) : The total digits of D, M and S and separator marks must be within 10 digits, or the sexagesimal couldn’t be shown completely.
