Double

Standard data type: 64 bit floating point

Syntax
   Dim variable As Double

Description
   Double is a 64-bit, floating-point data type used to store more precise 
   decimal numbers. They can hold positive values in the range 
   4.940656458412465e-324 to 1.797693134862316e+308, or negative values in 
   the range -4.940656458412465e-324 to -1.797693134862316e+308, or zero (0)
   . They contain at most 53 bits of precision, or about 15 decimal digits.

   Doubles have a greater range and precision than Singles, they still have 
   limited accuracy which can lead to significant inaccuracies if not used 
   properly.  They are dyadic numbers - i.e. they can only accurately hold 
   multiples of powers of two, which will lead to inaccuracies in most 
   base-10 fractions.
