Examples
{
# in bash:
# printf "%07.4f" 72.05785
# results in 72.0578
# but:
formatC(72.05785, digits = 4, width = 8, format = "f", flag = "0")
# results in
"072.0579"
# the goal is to obtain the same trunc number as using bash, then:
formatC(obs_trunc(72.05785, 4),
digits = 4,
width = 8,
format = "f",
flag = "0")
}
#> [1] "072.0578"
