MySQL how to convert decimal value to degree, minute, second

Question

I have a decimal value say 123.77

Now i want to convert it into corresponding degree, minute, second value using MySQ

Answer 1

Thinking out of the box, by borrowing a different Babylonian-based metric:

mysql> SELECT TIME_FORMAT("%H°%i'%s", SEC_TO_TIME(ROUND(3600 * -1.234)));
+-------------------------------------------------------------+
| TIME_FORMAT("%H°%i'%s", SEC_TO_TIME(ROUND(3600 * -1.234)))  |
+-------------------------------------------------------------+
| -01:14:02                                                   |
+-------------------------------------------------------------+
mysql> SELECT TIME_FORMAT("%H°%i'%s", SEC_TO_TIME(ROUND(3600 * -123.77)));
+--------------------------------------------------------------+
| TIME_FORMAT("%H°%i'%s", SEC_TO_TIME(ROUND(3600 * -123.77)))  |
+--------------------------------------------------------------+
| -123:46:12                                                   |
+--------------------------------------------------------------+

(The ROUND is to avoid getting 3 decimal places in the answer.)
