 [Maxima-bugs] [ maxima-Bugs-531466 ] float needs to be eval. with numer From: SourceForge.net - 2004-02-24 00:01:21 Bugs item #531466, was opened at 2002-03-18 13:09 Message generated for change (Comment added) made by macrakis You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=531466&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Daniel Lemire (lemire) Assigned to: Nobody/Anonymous (nobody) Summary: float needs to be eval. with numer Initial Comment: See below... we'd like to see "float(exp(exp(2)))" evaluated to 1618.177991912654. (C1) float(exp(exp(2))); 2 %E (D1) 2.718281828459045 (C2) float(exp(exp(2))),numer; (D2) 1618.177991912654 (C3) ---------------------------------------------------------------------- >Comment By: Stavros Macrakis (macrakis) Date: 2004-02-23 18:51 Message: Logged In: YES user_id=588346 More cases: float(%pi^%pi)=> 3.14^%pi; float(2^%pi) =>2.0^%pi; but float((%e+%pi)^2) => 34.3. The intent is to avoid floating powers of symbolic objects. For example, you don't want float(x^2)=>x^2.0 or float(x^ (1/3)) => x^0.333. But obviously this has been taken too far. If we can get a numerical result for the whole expression, we should (2^%e, %e^2, even %e^%pi). Numer and float just aren't very well thought-out. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=531466&group_id=4933
