| - | A cell type value can also be created from integral values, like [[Int Type|Integer]], [[Positive Int Type|Positive Integer]], [[Non Negative Int Type|Non Negative Integer]] etc, and from real values, like [[Double Type|Double]]. The mapping of numeric values and their corresponding cell type values can be seen below: | + | A cell type value can also be created from integral values, like [[Integer Value Type|Integer Value]], [[Positive Integer Value Type|Positive Integer Value]], [[Non Negative Integer Value Type|Non Negative Integer Value]] etc, and from real values, like [[Real Value Type|Real Value]].

| - | It is worth noting that the definition of maps with cell type “1 Bit Integer” helps saving memory, but it also has a huge negative impact in performance. | + | It is worth noting that the definition of maps with cell type "1 Bit Integer" helps saving memory, but it also has a huge negative impact in performance. On the other hand, the use the cell type "IEEE 754 64 Bit Real" uses way more memory than any other cell type. |
