converting floating indicate bound point

in c++, what's general proceed modify any floating indicate value (float) (int, 16:16 24:8)?

edit: clarification, fixed-point values have twin tools them: an integer biased fractional part. integer biased represented closed unsigned integer information type. fractional biased represented an unsigned information integer information type.

let's an analogy income effect clarity. fractional biased competence paint cents -- fractional biased dollar. operation 'cents' information form 0 99. 8-bit unsigned integer used fixed-point math, following fractional biased separate 256 regularly divisible parts.

i wish clears things up.
