To save space, \code{fwrite} prefers to write wide numeric values in scientific notation -- e.g. \code{10000000000} takes up much more space than \code{1e+10}. Most file readers (e.g. \code{\link{fread}}) understand scientific notation, so there's no fidelity loss. Like in base R, users can control this by specifying the \code{scipen} argument, which follows the same rules as \code{\link[base]{options}('scipen')}. \code{fwrite} will see how much space a value will take to write in scientific vs. decimal notation, and will only write in scientific notation if the latter is more than \code{scipen} characters wider. For \code{10000000000}, then, \code{1e+10} will be written whenever \code{scipen<6}.
