It is possible to accomplish this for the Chunk and to inline.
See in the example below: the real value, value with modification for inline and the modification to the Chunk.
The code below is in rmd
, and consists of head, print original values (Chunk 1), function for adjustment inline (Chunk 2), adjustment to print as a result (Chunk 3) and print values default to decimal places (Chunk 4).

## R Markdown
```{r }
mean(mtcars$mpg)
pi
```
\
Valor de pi é igual a `r pi`.
\
## MOD - INLINE
```{r , include=FALSE}
library(knitr)
inline_hook <- function (x) {
if (is.numeric(x)) {
res <- ifelse(x == round(x),
sprintf("%d", x),
sprintf("%.3f", x) # numero de casas decimais
)
paste(res, collapse = ", ")
}
}
knit_hooks$set(inline = inline_hook)
```
\
Valor de pi é igual a `r pi`.
\
## MOD - CHUNK
```{r , include=FALSE}
options(digits = 4)
```
```{r }
mean(mtcars$mpg)
pi
```
Source: inline.
I know with
format(X, nsmall=3)
it will show numbers like 1 and 1.5 as 1,000 and 1,500, but I don’t know of a global option for this.– Daniel R
options(digits) is considered a "suggestion"; any function that specifies the number of boxes to display some result will have provenance. If you are generating the documents via Pandoc, take a look at the function
pander::panderOptions

@Carloseduardolalike thanks! interesting this library Pander! Will help a lot!
