programming A number representation scheme where a number R
is represented by an integer N such that R=N*B, where B is
the (assumed) base of the representation.
On computers with no floating-point unit fixed-point
calculations can be significantly faster as all the operations
are basically integer operations. Apart from that,
fixed-point representation has the advantage of having uniform
density, i.e., the smallest resolvable difference of the
representation is B throughout the representable range, in
sharp contrast to floating-point representations.
