R: piping (%>%) not working with round(). Ex: 136/13.00 %>% round() = 10.46154

Question

why does 136/13.00 %>% round() return 10? The same input without the piper returns the correct value

136/13.00 %>% round()
[1] 10.46154
> round(136/13.00)
[1] 10
10.46154 %>% round()
[1] 10

Answer 1

Looks like operator precedence

(136/13) %>% 
          round
#[1] 10

We can also make it a bit more chainy

136 %>%
     `/`(13) %>%
     round
#[1] 10
