fixed-point part

8.4

The digits or bits after the decimal point that show fractional value in computer numbers

noun
/ˈfɪkst pɔɪnt pɑrt/

Specialized

: parte fraccionaria

To avoid overflow, adjust the scale so the fixed-point part fits within the available fractional bits.

Morphology

fixed-point + part

The phrase combines the compound technical term 'fixed-point' with the general noun 'part', so its basic sense as 'a component of a fixed-point number' is compositionally derivable from the constituents. However, the precise meaning — specifically the fractional digits after the radix point — is a domain-specific interpretation that a general B1 learner would not reliably infer from the words alone, so it is only partly transparent.

Etymology

Fixed-point part in computing names the digits after the decimal point — like the 'cents' in money — that show the fractional piece of a number. So the fixed-point part is what controls how exact the fraction is.
