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}\approx 2\times 10^{-10}
.
When the flag is on the precision is increased to machine epsilon
(i.e. \approx 10^{-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 |
