WebA floating-point (FP) number is a kind of fraction where the radix point is allowed to move. If the radix point is fixed, then those fractional numbers are called fixed-point numbers. The best example of fixed-point numbers are those represented in commerce, finance while that of floating-point is the scientific constants and values. 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 ...
