Hi,

I've got this:

```scheme
"helpers.rkt"> (format "~0,0F" 1.22)
"1."
"helpers.rkt"> (format "~0,0F" 1.55)
"2."

```

I'd be satisfied with the same without the decimal point. Is there a way?

The decimal point is always added when `~F` renders a number, even if it's an exact integer; this seems to be the traditional behavior; Common Lisp's `format` does it, as do functions like SRFI-48's that are influenced by it.

You can use [`~r`](https://docs.racket-lang.org/reference/strings.html#%28def._%28%28lib._racket%2Fformat..rkt%29._~7er%29%29) from the [`racket/format`](https://docs.racket-lang.org/reference/strings.html#%28part._format%29) module instead:

```scheme
> (~r 1.23 #:precision 0)
"1"
> (~r 1.55 #:precision 0)
"2"

```

Thanks! Do I have to use it with `format` like this?

```scheme
(format "~a~a" (~r qt #:precision 0) unit)

```

`~r` returns a string, so you can use `display`, [`write-string`](https://docs.racket-lang.org/reference/Byte_and_String_Output.html#%28def._%28%28quote._~23~25kernel%29._write-string%29%29), [`printf`](https://docs.racket-lang.org/reference/Writing.html#%28def._%28%28quote._~23~25kernel%29._printf%29%29), SRFI-48 `format`, etc. to print it. Lots of options.

Aside/blatent self-promotion: I suggest [my Racket port](https://docs.racket-lang.org/slib-format/index.html) of the Scheme version of Common Lisp `format` from SLIB instead of SRFI-48 for anything complicated as it supports far more functionality.

You can also use the `~a` function:

```scheme
(~a (~r qt #:precision 0) unit)

```
