The double.MinValue follows the .NET convention If you are going to use a function/value in a language/framework you are not familiar with, have a look at how it works or look up the extensive documentation first: "The value of this constant is negative 1.7976931348623157E+308."[1] "The value of the Epsilon property is not equivalent to machine epsilon, which represents the upper bound of the relative error due to rounding in floating-point arithmetic."[2] [1] http://msdn.microsoft.com/en-us/library/system.double.minvalue.aspx http://msdn.microsoft.com/en-us/library/system.double.minval...
