Why are answers dumbed down like that?

Every subexpression is considered independently, so float conversion
doesn't take place until the assignment is evaluated.  The type of the
lvalue does not propagate across every rvalue.

So it's procedural rather than deliberate/designed. It's not hard tocope withstill I'd vote to correct it -- one of those things where a look aheadcouldsorta say that if the lvalue is float, then all subsequent arithmeticwill be

float.  Or not worth the trouble, it's easy enough to work around.
