How does conversion from fixed-point to floating-point happen?

WebFor example, a fixed-point representation with four bits to the right of the binary point has a precision of 2-4 or 0.0625, which is the value of its least significant bit. Any number within the range of this data type and scaling can be represented to within (2 -4 )/2 or 0.03125, which is half the precision. WebJun 30, 2024 · These are (i) Fixed Point Notation and (ii) Floating Point Notation.
