Zero Suppression

concealment of zeroes, hiding of zeroes

Zero suppression is the removal of redundant zeroes from a number. This can be done for storage, page or display space constraints or formatting reasons, such as making a letter more legible.Examples:00049823 - 498237.678600000 - 7.67860032.3231000 - 32.3231It is also a way to store a large array of numbers, where many of them are zero, by omitting the zeroes, and instead storing the indices and values of the numbers that are non-zero. It only makes sense if the extra spaced used for storing the indices (on average) is smaller than the space saved by not storing the zeroes.
