#674: ##sys#string->number gets called without prefixes in the reader
-----------------------------+----------------------------------------------
Reporter: sjamaan | Owner: felix
Type: defect | Status: new
Priority: major | Milestone: 4.8.0
Component: core libraries | Version: 4.7.x
Resolution: | Keywords: reader, numbers
-----------------------------+----------------------------------------------
Comment(by felix):
Attached is a patch which I believe might help here - it pushes the
exactness conversion into `##sys#string->number`, via an additional
optional argument which is either `#f` (undetermined), the symbol `'i`
(inexact) or `'e` (inexact). On older chickens, the third argument will
always be false, so this should be backwards-compatible.
Is this useful?
We should also review the remaining hooks used in numbers
(`##sys#inexact?`, `##sys#inexact->exact`, `##sys#exact->inexact`, etc.).
Some of them might be redundant and allow us to optimize/rewrite core
procedures in better ways.
