Fixed Point and Floating Point Number Representations

WebApr 8, 2012 · The idea behind fixed-point arithmetic is that you store the values multiplied by a certain amount, use the multiplied values for all calculus, and divide it by the same amount when you want the result. The purpose of this technique is to use integer arithmetic (int, long...) while being able to represent fractions. WebA fixed-point data type is characterized by the word size in bits, the binary point, and whether it is signed or unsigned. The position of the binary point is the means by which fixed-point values are scaled and interpreted. With Fixed-Point Designer™, fixed-point data types can be integers, fractionals, or generalized fixed-point numbers. http://www.dspguide.com/ch4/2.htm cleveland clinic phone interview
