-122d 54m 8.41s W (DMS) to be converted as decimal (DD). I tried two different available online converters to do the calculation. Surprisingly outputs are different. It looks like they match up to
7th decimal places.
Out of curiosity, I used open-source
Only common ground from this observation I can find is up to
7th decimal places matches. I am new to this subject area. I am not sure which decimal value I have to trust if I want it to be converted back as original DMS value.
I wonder each on-line converter and external JS library I tried out has different logic when it comes to truncate
If I need to implement conversion programmatically either using an external library or math formula available on-line such as this: Converting latitude and longitude to decimal values, how far I have to trust in decimal places for DD value?
