Return boolean value for bool return type functions.

Return boolean value for bool return type functions.

Currently in some of the function which returns a bool, are returning int, which would be getting casted to boolean.
So, to eliminate the casting better return a boolean for bool return type functions.

NOTE: This change also removes the math element role.

This change also removes the math element role, which is fine - but please
include that in the change description.
