\title{Find Details of the Numerical Representations in the Current Locale}
\description{
  Get details of the numerical representations in the current locale.
}
\usage{
Sys.localeconv()
}
\value{
  A character vector with 18 named components. See your ISO C
  documentation for details of the meaning.

  It is possible to compile \R without support for locales, in which
  case the value will be \code{NULL}.
}
\seealso{
  \code{\link{Sys.setlocale}} for ways to set locales: by default \R uses the
  C clocal for \code{"LC_NUMERIC"} and \code{"LC_MONETARY"}.
}
\examples{
Sys.localeconv()
## The results in the default C locale are
##    decimal_point     thousands_sep          grouping   int_curr_symbol 
##              "."                ""                ""                "" 
##  currency_symbol mon_decimal_point mon_thousands_sep      mon_grouping 
##               ""                ""                ""                "" 
##    positive_sign     negative_sign   int_frac_digits       frac_digits 
##               ""                ""             "127"             "127" 
##    p_cs_precedes    p_sep_by_space     n_cs_precedes    n_sep_by_space 
##            "127"             "127"             "127"             "127" 
##      p_sign_posn       n_sign_posn 
##            "127"             "127"

## Now try your default locale (which might be "C").
