*To*: <srfi-77@xxxxxxxxxxxxxxxxx>*Subject*: ambiguous sign notation support?*From*: Paul Schlie <schlie@xxxxxxxxxxx>*Date*: Sat, 01 Jul 2006 11:36:50 -0400*Delivered-to*: srfi-77@xxxxxxxxxxxxxxxxx*Thread-index*: AcadJCtzajcJBwkXEduZsgADk1ictA==*Thread-topic*: ambiguous sign notation support?*User-agent*: Microsoft-Entourage/11.2.3.060209

Any possibility of considering a somewhat more numerically consistent abstract notation for ambiguously signed values? (i.e. ~nan.0 replaces the positively signed +nan.0 notation) Thereby enabling the optionally supported designations: ~inf.0 ~inf.0 -inf.0 -0.0 0 +0.0 +inf.0 <|------------------------|-----------------------|> <--------- -nan.0 -------> <-------- +nan.0 -------> <---------------------- ~nan.0 --------------------> (/ -0.0) => -inf.0 (/ 0) => ~inf.0 (or basic ~nan.0) (/ +0.0) => +inf.0 (/ -inf.0 +0.0) => -nan.0 (or basic ~nan.0) (/ ~inf.0 +0.0) => ~nan.0 (/ +inf.0 +0.0) => +nan.0 (or basic ~nan.0) Enabling a basic implementation to simply map: ~inf.0 -nan.0 +nan.0 => ~nan.0
