The conversion between decimal degrees and degrees minutes seconds is not equal or incorrect. Can anyone help or explain? I'm assuming it revolves around recurring numbers.
Converting 22°15'45.7" to decimal degrees using this online calculator, bigint ticked with the following formula:
((((45.7)/60+15)/60)+22) = 22.262694* (*4 recurs 608 times followed by a 5).
Using this number in reverse formula to get the seconds: ((22.262694-22)*60-15)*60 = 45.70* (*0 recurs 609 times followed by 205). This is not equal to 45.7.
Thanks in advance for your help,
because ttmath uses floating point numbers:
