[Message part 1 (text/plain, inline)]

Hello schemers,

the number->string procedure from (rnrs) should accept the optional
precision argument, but does not:

scheme@(guile-user)> (import (rnrs))
scheme@(guile-user)> (number->string 1.1 10 53)
;;; <stdin>:2:0: warning: possibly wrong number of arguments to `number->string'
ERROR: In procedure number->string:
ERROR: Wrong number of arguments to #<procedure number->string (_ #:optional _)>

The example should return "1.1|53".

Tested with GNU Guile 2.0.9.71-8d5d04.

Hi :)

Ignorant question: what is the precision argument good for?  FWIW
Guile's inexact reals are all 64-bit doubles.

Just curious :)
