Re: [scheme-requests-for-implementation/srfi-48] Fix test for Chicken (#12) hamay1010 14 Nov 2020 04:23 UTC

- The output of format ~F is dependent on number->string .
  ```
  ;; Chicken 5.2.0
  (number->string 3.4569e15) ; ==> "3456900000000000.0"
  (number->string 3.456e15)  ; ==> "3456000000000000.0"

  ;; Chicken 4.12.0
  (number->string 3.4569e15) ; ==> "3.4569e+15"
  (number->string 3.456e15)  ; ==> "3.456e+15"

  ;; Guile  2.2.7
  (number->string 3.4569e15) ; ==> "3.4569e15"
  (number->string 3.456e15)  ; ==> "3.456e15"

  ;; Gauche 0.9.9
  (number->string 3.4569e15) ; ==> "3.4569e15"
  (number->string 3.456e15)  ; ==> "3.456e15"
  ```

- Sorry, I don't remember why the old test-0001-Chicken.scm used
zero-padded exponent notation (e.g. "3.457e+015" ) .
  It might be something copy miss ( test-0001-Racket.scm uses "3.457e+015" ) .

It looks like this change simply changes the results to match what Chicken is doing, but shouldn't Chicken be giving the same results as other implementations?  On the other hand, I don't understand why the results used to zero-pad the exponent, and it looks like this change is making the Chicken results match the results for other implementations.  Is that right?
