WebAug 27, 2024 · For Simulink Display Values, as mentioned in the last sentence of my answer and in the image above it, there is a known limitation where six of the built-in integer types do not show binary, hex, or octal. As a result with Simulink Display Values, binary, hex, and octal will only be shown with int64, uint64, and fixed-point types. WebFeb 3, 2024 · I am having trouble to get the intuition behind the following approach: We take the fraction point (say: .642) and continuously multiply by 2, taking whatever ends up right of the point as our next number (either 0 or 1) after the fixed point in the binary number. Then we take whatever is left after the decimal point and repeat. binary
