 AbsoluteError
 compute the absolute error of an approximation

 Calling Sequence AbsoluteError(xe, xa, opts)

Parameters

 xe - realcons; the exact value xa - realcons; the approximated value opts - (optional) equation(s) of the form digits = value

Options

 • digits = posint
 A positive integer; the environment variable Digits will be set to this integer during the execution of this procedure. By default, Digits is 10.

Description

 • The AbsoluteError command computes the absolute error of xa with respect to the exact value xe.
