  round(x1,-1)
  arrondi(x1,-1)

  x2 <- c(-15,-25,-35,-45,-55)
  round(x2,-1)
  arrondi(x2, -1)

  x3 <- 1.125
  round(x3,2)
  arrondi(x3, 2)

  x4 <- seq(-0.55,0.55,0.1)
  data.frame(
    val = x4,
    round = round(x4,1),
    arrondi = arrondi(x4, 1),
    equal = (arrondi(x4, 1) == round(x4,1))
  )
