How do you convert a number to a fixed-point?

Lossy Conversion of Fixed-Point Numbers

To convert from floating-point to fixed-point, we follow this algorithm: Calculate x = floating_input * 2^(fractional_bits) Round x to the nearest whole number (e.g. round(x) ) Store the rounded x in an integer container.

How do you convert 0.8 to binary?

We can go on, but even now, we can see that decimal 0.8 is binary 0.11001100... (and many digits). In fact, it is a periodic number with period 1100, so we won't find the exact number of binary digits to write 0.8 precisely. It is 1100 all the way down.

How do you convert a fixed-point to a floating-point?

Converting from fixed-point to floating-point

Divide the number by 2^n (2 to the power of n).

What is fixed-point format?

In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar).
