Quasiperiodic function periodic functions and that article should be consulted. The more vague and general notion of quasiperiodicity has even less to do with quasiperiodic functions in the mathematical sense. A useful example is the function: If the ratio "A"/"B" is rational, this will have a true period, but if "A"/"B" is irrational there is no true period, but a succession of increasingly accurate "almost" periods. Quasiperiodic function In mathematics, a quasiperiodic function is a function that has a certain similarity to a periodic function. A function formula_1 is quasiperiodic with quasiperiod formula_2 if formula_3, where formula_4 is a ""simpler"" function than
