Values to the left of the decimal are generally called 'big' since they are larger than values to the right of the decimal. format_big() lets you update the settings of a rounding_specification object (see round_spec) so that values left of the decimal will be printed with a specific format (see examples).

format_big(rspec, mark = ",", interval = 3L)



a rounding_specification object (see round_spec).


a character value used to separate number groups to the left of the decimal point. See prettyNum for more details on this. Set this input to '' to negate it's effect.


a numeric value indicating the size of number groups for numbers left of the decimal.


an object of class rounding_specification.


big_x <- 1234567 rspec <- format_big(round_spec(), mark = '|', interval = 3) table_value(big_x, rspec) # returns "1|234|567"
#> [1] "1|234|567"
