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.

In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby.
