How to convert longitude and latitude to standard unit of degree and second

The formula should be: longitude and latitude in any decimal number. The integer is the degree, and the fractional part is the score in the integer part of the number obtained by multiplying the decimal part by 60, multiply the decimal part of the number by 60
The number is the number of seconds. For example, the number of degrees converted from 36.12432314 to second is: the number of degrees is "36", and the score is an integer of "0.12432314 × 60 = 7.4593884 ".
Number of "7", the second is "0.4593884 × 60 = 27.5639304", "27.6" ---- 36 ° 7' 27.6 seconds 〃.

Calculation principle: retain the entire part, decimal number x 60 longitude: 14 ° 0.32 × 60 = 19.2 -- "19' 0.2 × 60 = 1.2 --" 1.2 then: similarly, the latitude is 52.20 = 52 ° 12' 0 longitude 〃
