float and double datatype is good to store latitude and longitude? [duplicate]

Answer 1

It's not a matter of safety, its just a matter of precision. I wouldn't consider floats, but doubles are what i think are ideal here. You just need to see what's the most precision you can get out of a double and see if it fits a regular longitude/latitude value. I think it's more then enough.

Else BigDecimal is just a simple backdoor to your problem, use it if you want more precision

Answer 2

you will not have to do any rounding on your longitude or latitude values, so use whichever one you want. Double is more precise, so let that be the most important factor in your decision.

How much precision do your long/lat values need?

For pinpoint accuracy on a map, you might want to look at big decimal, but for vague values, float is good enough.

Answer 3

You should start with the accuracy you desire. Once you have determined that, you can choose a data type that is suitable.

If you decide that an accuracy of 5 decimal places (1.1132 m) is enough, you can easily go with float. The more accurate your calculation needs to be, the more you should lean towards using double and eventually BigDecimal.

When comparing floating point numbers, you should incorporate the necessary precision as well.
