WebThe basic idea for a lookup table is simple -- you use the fixed point value as an index into an array to look up the value. The problem is if your fixed point values are large, your tables become huge. For a full table with a 32-bit FP type you need 4*2 32 bytes (16GB) which is impractically large. So what you generally do is use a smaller ...

Web1 day ago · In decimal floating point, 0.1 + 0.1 + 0.1 - 0.3 is exactly equal to zero. In binary floating point, the result is 5.5511151231257827e-017. While near to zero, the differences prevent reliable equality testing and differences can accumulate. For this reason, decimal is preferred in accounting applications which have strict equality invariants.
