Format numbers with fixed decimal places — format

Round with round_half_away_from_zero() and format with a fixed number of decimal places. Decimal ties round half away from zero, and values that round to zero display as positive zero (for example, "0.0" rather than "-0.0").

Usage

format_number(x, digits = 1, width = NULL)

Arguments

x: A numeric vector.
digits: A non-negative, integer-valued scalar giving the number of decimal places.
width: NULL, or a non-negative, integer-valued scalar giving the minimum field width passed to base::formatC(). The default, NULL, does not set a minimum width.

Value

A character vector containing the formatted values.

Examples

format_number(c(1.25, -1.25), digits = 1)
#> [1] "1.3"  "-1.3"
format_number(c(6.25, -0.04), digits = 1, width = 5)
#> [1] "  6.3" "  0.0"
