Examples
# Basic usage
pretty_number(1234) # "1.23k"
#> [1] "1.23k"
pretty_number(1234567) # "1.23m"
#> [1] "1.23m"
pretty_number(1234567890) # "1.23b"
#> [1] "1.23b"
# Adjusting decimal places
pretty_number(1234, n_decimal = 1) # "1.2k"
#> [1] "1.2k"
# Adding a prefix
pretty_number(1234, prefix = "$") # "$1.23k"
#> [1] "$1.23k"
# Without rounding
pretty_number(1250, truncate = TRUE) # "1.2k"
