## Files in the Minitab portable worksheet format represent numbers in a
## fixed format (written in Fortran as 5e15.9 or something like that) but
## the data values are only stored in Minitab in single precision.  We use
## signif to remove the inaccuracies in the representation in the files.

"read.mtp" <-
function (file) {
    clean <- function(x) if(is.numeric(x)) signif(x, 6L) else x
    val <- .Call(read_mtp, file)
    lapply(val, clean)
}
