I was solving a task in flow through a pipe and noticed a result from int where floats were changed into a RootOf containing integers and fractions. I was surprised by the result. Here is a very simple example: f:=z->solve(y/(1.+(-0.5*y)^0.8)=z,y); v:=x->int(f,-10..x); v(-1); Is it common for Maple to change floats into integers and fractions for symbolic analysis? It seems to violate the rules. Thanks, Lee View 4238_Odd Solve Example.mw on MapleNet or
