Floating point versus fixed point: what are the pros/cons?
问题 Floating point type represents a number by storing its significant digits and its exponent separately on separate binary words so it fits in 16, 32, 64 or 128 bits. Fixed point type stores numbers with 2 words, one representing the integer part, another representing the part past the radix, in negative exponents, 2^-1, 2^-2, 2^-3, etc. Float are better because they have wider range in an exponent sense, but not if one wants to store number with more precision for a certain range, for example
