exp
→ exp()Raises the number e (2.71828…) to the power you give.
exp(maemo)exp(1) is 2.718281828…, the number called e. exp(0) is 1. exp(2) is e × e.
e is the number that turns up wherever things grow or fade at a rate that depends on their own size — heat leaving a room, a population rising. Where pow grows by a power you set, exp is growth as it happens in nature.
log is exp turned around: log(exp(3)) is 3.
The name is left as it stands. exp is short for “exponential”, notation that is not translated in Botswana teaching materials.
