From: Alan Watson Date: Wed, 30 May 2007 14:33:05 -0500 Subject: [Formal] number->string and put-datum have different restrictions for inexact arguments Submitter: Alan Watson Issue type: Enhancement Priority: Minor Component: Base Library Chapter 9 and Library Chapter 8 Version: 5.93 Summary: When number->string is used on an inexact number and the radix is 10, it is required to produce the minimum number of mantissa digits that satisfy eqv? invariance with string->number. However, put-datum does not have any similar restriction on the number of mantissa digits. I would suggest that the behaviour of these two procedures be made more similar (i.e, apply the minimum digits requirement to put-datum or drop the minimum digits requirement on number->string) or a note be added to explain why they are different. RESPONSE: The pertinent aspect of this is the `put-datum'/`get-datum' invariance with respect to `equal?'. A specification of this invariance has been added.
