I am trying to save a float number which is this long
13.00386644742523
Its basically Lat and Lng value.
when i save it in the database its getting stored as
13.0039
Based on experience I did this for a navigation database built from ARINC424 and eventually used a DECIMAL(18,12) for storing values in radians.
NOTE: Floats and doubles aren’t as precise and may result in rounding errors
The point is that when using degrees or radians we know the range of the values – and the fractional part needs the most digits.
The best way is to use MySQL Spatial Extensions
