Fixed point to floating point

WebA fixed-point number consists of a number of integers and a number of fractions. Its value = the integer's complement of its binary code divided by 2^fractional bit width . For example, if the integer bit width is 8 and the fractional bit width is 8, the following table shows some fixed-point values: WebHere's a side to a classic computer architecture debate: floating-point vs. fixed-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. WebFeb 6, 2007 · The advantages of floating-point processors are well known. Without a doubt, floating point implementations of many algorithms take fewer cycles to execute than fixed point code (assuming, of course, that the fixed-point code offers similar precision).
