A process for generating estimated functional values at arbitrary locations beginning with a set of known functional values At the known values, the approximated values need not equal the known values This distinguishes an approximation from an interpolation
A value that is nearly, but not exactly, correct Numerical approximations often result from using a small number of significant digits Approximation also refers to using a simpler model of a process, to make predictions easier
the act of bringing near or bringing together especially the cut edges of tissue the quality of coming near to identity (especially close in quantity) an imprecise or incomplete account; "newspapers gave only an approximation of the actual events
An approximation is a number, calculation, or position that is close to a correct number, time, or position, but is not exact. Clearly that's an approximation, but my guess is there'll be a reasonable balance. = estimate
An approximation is a fact, object, or description which is similar to something else, but which is not exactly the same. That is a fair approximation of the way in which the next boss is being chosen
