+double
+======
+
+Desciption
+----------
+
+Double precision floating point number. Occupies 4 bytes.
+
+
+
+The double implementation on the Arduino is currently exactly the
+same as the float, with no gain in precision.
+
+
+
+Tip
+---
+
+Users who borrow code from other sources that includes double
+variables may wish to examine the code to see if the implied
+precision is different from that actually achieved on the Arduino.
