Product: D Version: D2 Hardware: All OS: All Status: NEW Keywords: wrong-code Severity: major Priority: P1 Component: druntime Assignee: nobody@puremagic.com Reporter: k.hara.pg@gmail.com Test case: void main() { alias F = float; F f1 = +0.0, f2 = -0.0; assert(f1 !is f2); // they have different bit representations assert(f1 == f2); // but they are equal TypeInfo ti = typeid(F); assert(ti.getHash(&f1) == ti.getHash(&f2)); // if f1 and f2 are equal, their hash values should also be equal } -- |
