In computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing.The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation.

Specifically, many of the size limitations of previous versions were greatly increased. To illustrate, the number of rows was now 1,048,576 (2 20) and the columns was 16,384 (2 14; the far-right column is XFD). This changes what is a valid A1 reference versus a named range.
The main idea of the method is to partition the matrix into small square blocks of size t × t for some parameter t, and to use a lookup table to perform the algorithm quickly within each block. The index into the lookup table encodes the values of the matrix cells on the upper left of the block boundary prior to some operation of the algorithm ...
4-3-2-1. The countdown is on when it comes to preparing for a good night’s sleep. Dr. Roban suggests no alcoholic beverages at least four hours before bed; no heavy or spicy foods at least three ...
Labeled as "ex-burbs," these areas are usually 40-60 miles away from major metropolitan cities and can offer more peaceful ways of life and "affordable housing" options.
A two byte raw data value would require a minimum table size of 65,536 bytes – to handle all input possibilities – whilst allowing just 256 different output values. However, this direct translation technique provides an extremely fast validation & conversion to a (relative) subroutine pointer if the heuristics , together with sufficient ...
Two days later, the Buffalo Bills clinched a spot. The Bills are the only team to defeat the 13-1 Chiefs this season, and therefore hold a potential tiebreaker for the No. 1 seed in the AFC and ...
To make such a formula, one replaces a number with a cell reference. For instance, the formula =5*C10 would produce the result of multiplying the value in cell C10 by the number 5. If C10 holds the value 3 the result will be 15. But C10 might also hold its formula referring to other cells, and so on.
