DESCRIPTION
|
|
Without args, epsilon() returns the current epsilon value.
|

|
|
With one arg, epsilon(eps) returns the current epsilon value
|

and sets the stored epsilon value to eps.
|
|
|
|
The stored epsilon value is used as default value for eps in
|
|
the functions appr(x, eps, rnd), sqrt(x, eps, rnd), etc.
