Re: Inefficient "solve" in Pari 2.0.18 (beta) ? 

Thanks to Will Galway, the corrected solve function is much faster

? \p400
   realprecision = 404 significant digits (400 digits displayed)
? solve(x=-2,2,cos(x)-x)
%12 = 0.7390851332151606416553120876738734040134117589007574649656806357732846548835475945993761069317665318498012466439871630277149036913084203157804405746207786885249038915392894388450952348013356312767722315809563537765724512043734199364335125384097800343406467004794021434780802718018837711361382042066316335037277991696731223230061388658203621770810997897062684240588094898683261860600485898958548725736
