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.

	Doubles have a greater range and precision than KeyPgSingleSingles, 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.
