Double Klondike Double Klondike Double Klondike is a variant on the playing card game popularly known either as Solitaire or Snap-Up Patience, specifically a variant on the most well-known version of the game, Klondike. It is sometimes referred to simply as "Double Solitaire". Triple Solitaire, Quadruple Solitaire, etc. is also possible and is played. It is not to be confused with the single-player game of Gargantua which is also known as Double Klondike. As the name suggests, Double Klondike is a two-player game, and is played with two full packs of playing cards, minus the Jokers; for the purpose of Double Klondike,
Quadruple-precision floating-point format implement nearly quadruple precision using "pairs" of double-precision values is sometimes called double-double arithmetic. Using pairs of IEEE double-precision values with 53-bit significands, double-double arithmetic can represent operations with at least a 2×53=106-bit significand (actually 107 bits except for some of the largest values, due to the limited exponent range), only slightly less precise than the 113-bit significand of IEEE binary128 quadruple precision. The range of a double-double remains essentially the same as the double-precision format because the exponent has still 11 bits, significantly lower than the 15-bit exponent of IEEE quadruple precision (a range of for double-double versus for
