They should even work + if "s" is a "power" object, as long as the exponent is non-integer, but with + some limitations. For example, you can "collect(a*2^x+b*2^x, 2^x)" to get + "(a+b)*2^x", but "degree(2^(3*x), 2^x)" yields 0 instead of 3). +* Speedup in expand(). +* Faster Bernoulli numbers (Markus Nullmeier). +* Fixed a bug where quo() would call vector::reserve() with a negative + argument. +* Several small bugfices in code generation, output and documentation. + +1.0.2 (19 December 2001) +* Input parser recognizes "sqrt()", which is also used in the output. +* divide(a,b,q) only modifies q if the division succeeds; also, divide(a,b,a) + works now. +* Fixed small bug in dummy index renaming which could cause it to not + recognize renamable indices in some cases. +* power::degree() and power::ldegree() throw an exception when encountering + a non-integer exponent. +* Add output-support for Python bindings. + +1.0.1 (22 November 2001) +* Function sqrfree() handles a few more cases now. +* Class relational has real canonical ordering now. +* Handle obscene libreadline version numbers when building ginsh. + 1.0.0 (6 November 2001) * Some internal reorganization resulting in a general speed-up. * The last 3 evaluated expressions in ginsh are now referred to with the
