Re: Determining when Math::BigFloat is necessary?

Just out of curiousity, what measurements are too big for perl? GPS readings to meter accuracy can be stored in native data types, so what kind of gear is getting you more accuracy?

I haven't had problems with latitude/longitude/altitude, it's the elusive 'measurement' that shapefiles can contain that have been causing grief. The measurement value can be pretty much anything, if the lat/lon of the point represents a point in a river, the measurement might indicate flow rate, water temperature, depth, salinity, radioactivity, whatever it is that you need to measure for your application.
