E _ _ _ _ _ _ _ _ _ _ _ _ constant

The constant e is reserved for use as the base of the natural logarithm. Its value is approximately 2.71828284590, which REDUCE gives to the current decimal precision when the switch rounded is on.

emay be used as an iterative variable in a for statement, or as a local variable or a procedure. If e is defined as a local variable inside the procedure, the normal definition as the base of the natural logarithm would be suspended inside the procedure.
