Q:

what is the number used by apple geolocation

Whenever we use the geolocation api we get a number like 3.234345 for latitude and longitude which basically describes our position. 
Is the number in radians ? what exactly is this number and what does it mean.
Sorry I tried searching a lot of places but could not find an answer,
Would appreciate it if some one can help me understand

A:

I finally figured it out. It is called Decimal Degrees and is used by Apple , Google maps etc.
