[cmucl] #92: Type-derivation for log is inconsistent

#92: Type-derivation for log is inconsistent --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 2014-02 Keywords: | --------------------+------------------------------------------------------- Consider {{{ (defun foo (x) (declare (type (double-float 0d0) x)) (log x)) }}} When compiled, the compiler says the return type for {{{foo}}} is {{{(OR DOUBLE-FLOAT (COMPLEX DOUBLE-FLOAT))}}}. This is inconsistent with the return value of {{{(log 0d0)}}} and {{{(log -0d0)}}} which is {{{EXT :DOUBLE-FLOAT-NEGATIVE-INFINITY}}} (when the {{{:DIVIDE-BY-ZERO}}} trap is disabled). The correct derived type should be just {{{DOUBLE-FLOAT}}}. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/92> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.

[cmucl] #93: 4d-324 signals a reader error but shouldn't?

#93: 4d-324 signals a reader error but shouldn't? --------------------+------------------------------------------------------- Reporter: rtoy | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: Core | Version: 2014-02 Keywords: | --------------------+------------------------------------------------------- At the repl, 4d-324 throws a reader error. But the nearest float to 4d-324 is {{{least-positive-double-float}}} so we should probably return that instead of throwing an error. But values less than {{{0.5 * least-positive-double-float}}} could be rounded to 0, but I think the reader error is still appropriate. CLHS 2.3.1.1 says exponents that are out of range should signal a reader error. -- Ticket URL: <http://trac.common-lisp.net/cmucl/ticket/93> cmucl <http://common-lisp.net/project/cmucl> Cmucl is a high-performance, free Common Lisp implementation.
