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 :)
