Methods for Function rstream.incprecision in Package ‘rstream’

Description

Get and change the flag for increased precision of an "rstream" object in package rstream.

If the increased precision flag is on (TRUE) the "rstream" object returns random numbers with precision close to machine epsilon.

Most sources of pseudo random numbers generate random numbers of precision 2^(-32) ~ 2.e-10. When the flag is on the precision is increased to machine epsilon (i.e. ~ 1.e-16) by combining two random numbers of default precision.

Usage

## S4 method for signature 'rstream'
rstream.incprecision(stream)
rstream.incprecision(stream) <- value

Arguments

`stream`	an "rstream" object.
`value`	a boolean (`TRUE` or `FALSE`) to change the status of the flag.

Methods

Methods available for the following "rstream" subclasses: rstream.mrg32k3a.

Examples

## create a new rstream object (of subclass rstream.mrg32k3a)
s <- new("rstream.mrg32k3a")

## set increased precision flag of rstream object
rstream.incprecision(s) <- TRUE

## get increased precision flag of rstream object
rstream.incprecision(s)
