Rounding of Numbers

Rounds the values in its first argument to the specified number of decimal places (default 0). Importantly, round5() does not use Base R's "round to even" default. Standard rounding methods are implemented, for example, cards::round5(0.5) = 1, whereas base::round(0.5) = 0.

round5(x, digits = 0)

Arguments

x

(numeric)
a numeric vector

digits

(integer)
integer indicating the number of decimal places

Value

a numeric vector

Details

Function inspired by janitor::round_half_up().

Examples

x <- 0:4 / 2
round5(x) |> setNames(x)
#>   0 0.5   1 1.5   2 
#>   0   1   1   2   2 

# compare results to Base R
round(x) |> setNames(x)
#>   0 0.5   1 1.5   2 
#>   0   0   1   2   2
