Exponential


 * This page describes the monadic arithmetic function. For the dyadic function, see Power (function).

is a monadic scalar function which computes the exponential function (i.e. the power of Euler's constant e) of the argument. Exponential shares the glyph  with the dyadic arithmetic function Power.

Examples
Euler's constant itself can be obtained by supplying 1 as the argument.

On APL implementations that support complex numbers, one can demonstrate Euler's identity (with the help of Pi Times ):

Properties
Exponential is a special case of Power with the default left argument of e.

Exponential and natural log  are inverses of each other, except where the natural log is undefined.
