In terms of number of precision it can be stated as double has 64 bit precision for floating point number (1 bit for the sign, 11 bits for the exponent, and 52* bits for the value), i.e. The only difference it has from lambda expressions is that this uses direct reference to the method by name instead of providing a delegate to the method. Stephan van Hulst wrote:Keep in mind that doubles don't overflow.If you have a double variable with a positive finite starting value and you keep adding to it or multiplying it with a finite positive amount, eventually it will reach Double.MAX_VALUE, and stay there.If the value you add or multiply it with is small enough, it won't even ever reach Double.MAX_VALUE, instead settling at a lesser value..
