Converting minutes and seconds to decimal format

ØPress to convert minutes and seconds (sexagesimal figure) to decimal format. When you enter the sexagesimal figure, enter the degrees to the left of the decimal point, and minutes and seconds to the right—the first and second digits to the left of decimal point are minutes and the third and subsequent digits seconds.

IÅ Press to convert decimal format to sexagesimal format.
