Round a value to a defined number of significant digits printing out trailing zeros, if applicable

pretty_signif(x, digits = 6, sci_range = 6, sci_sep = "e")

Arguments

x: The number to round.
digits: integer indicating the number of significant digits.
sci_range: integer (or Inf) indicating when to switch to scientific notation instead of floating point. Zero indicates always use scientific; Inf indicates to never use scientific notation; otherwise, scientific notation is used when abs(log10(x)) > sci_range.
sci_sep: The separator to use for scientific notation strings (typically this will be either "e" or "x10^" for computer- or human-readable output).

A string with the value.

Values that are not standard numbers like Inf, NA, and NaN are returned as "Inf", "NA", and NaN.
