          Issue ID: 18054
           Summary: Wrong cast of float constant to bool
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: rumbu rumbu.ro

Any float constant between -1 and 1 cast to bool will return false:

float f = float.min_normal;

bool fcast1 = cast(bool)f;
bool fcast2 = cast(bool)(float.min_normal);

assert(fcast1); //ok
assert(fcast2); //error;
