Fixed point to floating point

WebMay 10, 2012 · public struct FIXED { public short fract; public short value; } that you want to convert to floating point. Such fixed-point numbers can be converted like this var fix = new FIXED { value = 42, fract = 16384 }; double floating = fix.value + (double)fix.fract / 65536; I divide by 65536 because a short is 16 bits (2^16).

WebFixed point arithmetic is a different world from floats. Depending on how convoluted your algorithm is, precission gets affected. It is quite common that systems converging with floats don't converge with fixed point. And I'm not sure if an ap_fixed<265,200> has any advantage compared to floats. To start with, you lose the dynamic range.
