fmt(x, digits = 2L, zeros = digits < 4L, ...)

Arguments

x	Numeric vector to be rounded or formatted.
digits	Integer, number of decimal places. Default is 0 for round2, 2 for fmt.
zeros	Logical, whether to keep trailing zeros. Default is TRUE if digits < 4 (fmt only).
...	Additional arguments passed to format() (fmt only).
