"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 ... " - Fixed point to floating point conversion
