WebAug 17, 2024 · 1 I am fairly new to python is there a fast way to convert decimal to 16-bit fixed-point binary (1-bit sign – 7-bit integer – 8-bit fraction) and back in python. I would like to manipulate the binary and convert this manipulated binary back to decimal. Example 1.25 -> 00000001.01000000 Manipulate first fraction part (0->1) 00000001.11000000 -> 1.75 WebInsulate the unsupported function with a cast to double at the input, and a cast back to a fixed-point type at the output. You can then continue converting your code to fixed point, and return to the unsupported function when you have a suitable replacement (Table 2).
