#### Description

The e function pushes on the stack a symbolic representation of the constant $e$.

Application of the →NUM operator returns its closest approximation to 2000-digits accuracy, irrespective of the numeric precision defined by SETPREC. This is done to ensure maximum accuracy if the symbolic expression is ultimately converted to a real number.

#### Compatibility

e is not fully equivalent to its userRPL counterpart.

In particular:

• userRPL returns the closest approximation of $e$ to 12-digits accuracy.

#### Usage

Input

« 6 SETPREC
e →NUM
DUP
1 *
