1 Description

This argument defines

ε_{r}

, which is intended to be a measure of the accuracy with which the problem functions

F (x)

and

c (x)

can be computed

Used by: functionprecision in e04ucf and e04uff (no CPP interface).

CommE04WB::setter_functionprecision returns a reference to the communication class itself.

2 Specification

FunctionPrecision(double value = Default =ε0.9 )

FunctionPrecision(double value = Default =ε0.9 , OptionalE04UE opt)

3 Arguments

1: $value$ – double Scalar: On entry: the required value of the argument.; Default:
Default $= ε^{0.9}$
2: $opt$ – OptionalE04UE Scalar: Optional argument container, derived from Optional.
