Fixed point to floating point
WebAug 4, 2010 · Converting from a floating-point value to a fixed-point value involves the following steps: Multiply the float by 2^ (number of fractional bits for the type), eg. 2^8 for 24.8 Round the result (just add 0.5) if necessary, and floor it (or cast to an integer type) leaving an integer value. Assign this value into the fixed-point type. WebHow to convert floating point algorithm to fixed point? The 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.
